Day 4: I will repost this guide daily until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and transaction fees are low. ARE YOU PART OF THE SOLUTION? News: Unconfirmed TX's @ 174K, more exchanges adding SegWit, Core prioritizes SegWit GUI

NOTE Just a daily repost because original OP Bastiat seems to be offline (due to holidays I guess). However, this is quite important as I see much misinformation on which exchanges use segwit or not. Please upvote for awareness.
BACKGROUND
Subhan Nadeem has pointed out that:
If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
A few thousand bitcoin users from /Bitcoin switching to making their next transactions SegWit transactions will help take pressure off the network now, and together we can encourage exchanges/wallets to rapidly deploy SegWit for everyone ASAP. Let's make it happen. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin
IMPORTANT NOTE: The mempool is currently overflowing. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange
SELECTED TOP EXCHANGES BY SEGWIT & BATCHING STATUS
There are 2 different Segwit address formats.
  • p2sh - starting with a "3..."
  • bech32 - starting "bc1..."
Not many wallets/exchanges support bech32 yet and will claim the address is invalid if you try to send to it. bech32 ("native Segwit") is a mildly better solution compared to p2sh.
Exchange Batching Status Segwit (p2sh) Send to bech32

If I'm a HODLer, will it help to send my BTC to a SegWit address now?
  • No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unneccessary transactions for now.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
  • The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download Electrum v3.0.3 to generate a SegWit address.
    A transaction between two SegWit addresses is a SegWit transaction.
    A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction.
    A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a SegWit Transaction if the sending address is a SegWit address.

So what address can I send to safely, there is so much confusion?
  • As of right now...
Non-Segwit Transactions
non-Segwit address to…
non-Segwit address OK
3..... (Segwit) OK
bc1.... (Segwit) No (no support for them yet)
Segwit Transactions

What wallet are you using to "batch your sends"? And how can I do that?
  • Using Electrum, the "Tools" menu option: "Pay to many".
    Just enter your receive addresses and the amounts for each, and you can send multiple transactions for nearly the price of one.
Why doesn't the Core Wallet yet support SegWit?
  • The Core Wallet supports SegWit, but its GUI doesn't. The next update will likely have GUI support built-in
Why isn't a large exchange like Coinbase SegWit ready & deployed when much smaller exchanges already are? Why do they default to high fees? Where is the leadership there?

Edit: Updated Segwit Exchange Status for Binance and HitBTC
submitted by Bastiat to Bitcoin [link] [comments]

Day 8: I will post this guide regularly until available solutions like SegWit, order batching, and Lightning payment channels are mass adopted, the mempool is empty once again, and tx fees are low. BTC Core SegWit GUI coming May 1, Coinbase incompetence exposed, more exchanges deploy SegWit

BACKGROUND
Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, and the majority of users have not made the switch themselves.
On Dec 18 2017 Subhan Nadeem has pointed out that: If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
Mass SegWit use alone could empty the mempool, result in blocks that are not completely full, and make it possible to include transactions with $0 fee once again.
On Jan 11 2018 when BTC sends went offline at Coinbase the mempool began to rapidly empty. Later in the day when service was restored there was a sharp spike up in the mempool. Subsequently, that afternoon Brian Armstrong finally had to break his silence on the topic and admitted Coinbase is working on SegWit but has still not deployed it. It appears that the high fees bitcoin is experiencing could be easily addressed and need not exist.
SegWit is just one technique available to exchanges and users to reduce pressure on the Bitcoin network. You can make the switch to SegWit on your next transaction, and pressure exchanges to deploy SegWit NOW along with other actions that will reduce their transaction impact on the network. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. If your wallet is not committed to implementing SegWit fast, speak out online any way you can and turn up the pressure. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed/ready exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin.
  4. Spread the word! Contact individuals, websites, etc that use bitcoin, explain the benefits of SegWit to everyone, and request they make the switch. Use social media to point out the benefits of SegWit adoption.
IMPORTANT NOTE: The mempool is currently still quite backlogged. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange.
BEYOND SEGWIT - BATCHING, PAYMENT CHANNELS, LIGHTNING
Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it. Users should demand this or walk.
Beyond SegWit & Batching, Lightning Network integration will have even more effect. Lightning is now active and exchanges could setup payment channels between each other so that on-chain transactions need not take place. Some ideas have to outline how that might work are here: Google Doc - Lightning Exchanges. Which two bitcoin exchanges will be the first to establish a lightning channel between themselves and offer free/instant transfers between them for their customers? This will happen in 2018

If I'm a HODLer, will it help to send my BTC to a SegWit address now?
No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unnecessary transactions for now.
Why is SegWit adoption going so slowly? Is it a time-consuming process, is there risk involved, is it laziness, or something else?
SegWit will require some extra work to be done right and securely. Also, most exchanges let the user pay the fee, and up to now users have not been overly concerned about fees so for some exchanges it hasn't been a priority.
Once Segwit is FULLY adopted, what do we see the fees/transaction times going to?
Times stay the same - fees will go down. How much and for how long depends on what the demand for transactions will be at that time.
What determines bitcoin transaction fees, to begin with?
Fees are charged per byte of data and are bid up by users. Miners will typically include the transaction with the highest fee/byte first.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download the latest version of Electrum to generate a SegWit address.
A transaction between two SegWit addresses is a SegWit transaction.

P2SH/bech32 FAQs
What are the two SegWit address formats and why do they exist?
It's been a challenge for wallet developers to implement SegWit in a way that users can easily and without too much disruption migrate from legacy to SegWit addresses. The first wallets to enable SegWit addresses – Ledger, Trezor, Core, GreenAddress – use so-called “nested P2SH addresses.” This means they take the existing Pay 2 Script Hash address – starting with a “3” – and put a SegWit address into it. This enables a high grade of compatibility to exist wallets as every wallet is familiar with these addresses, but it is a workaround which results in SegWit transactions needing around 10 percent more space than they otherwise would.
Electrum 3.0 was the first wallet to use bech32 addresses instead of nested p2sh addresses.
Source: BTCManager.com
What is the difference in address format between SegWit address formats P2SH and bech32?
P2SH starts with "3..."
bech32 starts with "bc1..."
Which addresses can I send from/to?
P2SH Segwit addresses can be sent to using older Bitcoin software with no Segwit support. This supports backward compatibility
bech32 can only be sent to from newer Bitcoin software that support bech32. Ex: Electrum
Source: BitcoinTalk.org
Why did ThePirateBay put up two Bitcoin donation addresses on their frontpage, one bech32 and one not?
The address starting with a "3..." is a P2SH SegWit address that can be sent BTC from any bitcoin address including a legacy address. The address starting with a "bc1..." is a bech32 SegWit address that can only be sent to from newer wallets that support bech32.

Day 7: I will post this guide regularly until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and tx fees are low. Do you want low tx fees, because this is how you get low tx fees

TL/DR
Bitcoin users can help lower transaction fees and improve bitcoin by switching to SegWit addresses and encourage wallets/exchanges to do the same.
SUMMARY
Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, some admitting in December 2017 that they have not even started work on integrating it. Others, such as Zebpay in India have already implemented SegWit and are reaping the benefits of reduced transaction fees. If bitcoin users demand SegWit now it will temporarily relieve the transaction backlog while more even more advanced solutions such as Lightning are developed.
Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it.
There is an opportunity now for all bitcoin users to individually contribute to help strengthen and improve the bitcoin protocol. At this point, the process requires a bit of work/learning on the part of the user, but in doing so you'll actually be advancing bitcoin and leaving what could turn out to be a multi-generational legacy for humanity.

Edit: Bitonic batching status updated to 'Yes'
submitted by Bastiat to Bitcoin [link] [comments]

Day 9: I will post this guide regularly until available solutions like SegWit, order batching, and Lightning payment channels are mass adopted, the mempool is empty once again, and tx fees are low. Have you done your part?

BACKGROUND
Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, and the majority of users have not made the switch themselves.
On Dec 18 2017 Subhan Nadeem has pointed out that: If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
Mass SegWit use alone could empty the mempool, result in blocks that are not completely full, and make it possible to include transactions with $0 fee once again.
On Jan 11 2018 when BTC sends went offline at Coinbase the mempool began to rapidly empty. Later in the day when service was restored there was a sharp spike up in the mempool. Subsequently, that afternoon Brian Armstrong finally had to break his silence on the topic and admitted Coinbase is working on SegWit but has still not deployed it. It appears that this is an important data point that indicates if just a few major exchanges would deploy SegWit the high fees bitcoin is experiencing would be eliminated.
SegWit is just one technique available to exchanges and users to reduce pressure on the Bitcoin network. You can make the switch to SegWit on your next transaction, and pressure exchanges to deploy SegWit NOW along with other actions that will reduce their transaction impact on the network. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. If your wallet is not committed to implementing SegWit fast, speak out online any way you can and turn up the pressure. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed/ready exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin.
  4. Spread the word! Contact individuals, websites, etc that use bitcoin, explain the benefits of SegWit to everyone, and request they make the switch. Use social media to point out the benefits of SegWit adoption.
IMPORTANT NOTE: The mempool is currently still quite backlogged. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange.
BEYOND SEGWIT - BATCHING, PAYMENT CHANNELS, LIGHTNING
Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it. Users should demand this or walk.
Beyond SegWit & Batching, Lightning Network integration will have even more effect. Lightning is now active and exchanges could setup payment channels between each other so that on-chain transactions need not take place. Some ideas have to outline how that might work are here: Google Doc - Lightning Exchanges. Which two bitcoin exchanges will be the first to establish a lightning channel between themselves and offer free/instant transfers between them for their customers? This will happen in 2018

FAQs
If I'm a HODLer, will it help to send my BTC to a SegWit address now?
No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unnecessary transactions for now.
Why is SegWit adoption going so slowly? Is it a time-consuming process, is there risk involved, is it laziness, or something else?
SegWit will require some extra work to be done right and securely. Also, most exchanges let the user pay the fee, and up to now users have not been overly concerned about fees so for some exchanges it hasn't been a priority.
Once Segwit is FULLY adopted, what do we see the fees/transaction times going to?
Times stay the same - fees will go down. How much and for how long depends on what the demand for transactions will be at that time.
What determines bitcoin transaction fees, to begin with?
Fees are charged per byte of data and are bid up by users. Miners will typically include the transaction with the highest fee/byte first.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download the latest version of Electrum to generate a SegWit address.
A transaction between two SegWit addresses is a SegWit transaction.
A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction.

P2SH/bech32 FAQs
What are the two SegWit address formats and why do they exist?
It's been a challenge for wallet developers to implement SegWit in a way that users can easily and without too much disruption migrate from legacy to SegWit addresses. The first wallets to enable SegWit addresses – Ledger, Trezor, Core, GreenAddress – use so-called “nested P2SH addresses.” This means they take the existing Pay 2 Script Hash address – starting with a “3” – and put a SegWit address into it. This enables a high grade of compatibility to exist wallets as every wallet is familiar with these addresses, but it is a workaround which results in SegWit transactions needing around 10 percent more space than they otherwise would.
Electrum 3.0 was the first wallet to use bech32 addresses instead of nested p2sh addresses.
Source: BTCManager.com
What is the difference in address format between SegWit address formats P2SH and bech32?
P2SH starts with "3..."
bech32 starts with "bc1..."
Which addresses can I send from/to?
P2SH Segwit addresses can be sent to using older Bitcoin software with no Segwit support. This supports backward compatibility
bech32 can only be sent to from newer Bitcoin software that support bech32. Ex: Electrum
Source: BitcoinTalk.org
Why did ThePirateBay put up two Bitcoin donation addresses on their frontpage, one bech32 and one not?
The address starting with a "3..." is a P2SH SegWit address that can be sent BTC from any bitcoin address including a legacy address. The address starting with a "bc1..." is a bech32 SegWit address that can only be sent to from newer wallets that support bech32.

Day 6: I will post this guide regularly until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and tx fees are low. Refer a friend to SegWit today. There's no $10 referral offer, but you'll both get lower fees and help strengthen the BTC protocol

TL/DR
Bitcoin users can help lower transaction fees and contribute to bitcoin by switching to SegWit addresses and encourage wallets/exchanges to do the same.
SUMMARY
Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, some admitting in December 2017 that they have not even started work on integrating it. Others, such as Zebpay in India have already implemented SegWit and are reaping the benefits of reduced transaction fees. If bitcoin users demand SegWit now it will temporarily relieve the transaction backlog while more even more advanced solutions such as Lightning are developed.
Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it.
There is an opportunity now for all bitcoin users to individually contribute to help strengthen and improve the bitcoin protocol. At this point, the process requires a bit of work/learning on the part of the user, but in doing so you'll actually be advancing bitcoin and leaving what could turn out to be a multi-generational legacy for humanity.

An in-depth overview of different mobile wallets

Disclaimer: A lot of time went into writing this and more research than I anticipated. Errors are not just possible, they are certain. If you find any mistakes, please reach out to me and I'll edit. Furthermore I know I probably missed a couple apps, there are a lot out there. If I missed a big one, then again contact me and I'll consider adding it. If you are reading this in the future, note that these apps update regularly, anything mentioned here may have changed by the time you are reading it.

What is a mobile wallet?

A mobile Bitcoin wallet is an application for a mobile device which acts as a lightweight wallet and allows you to store, send and receive Bitcoin (or other cryptocurrencies and tokens). Mobile wallets use SPV (Simplified Payment Verification) to allow wallet functionality without having to download the whole blockchain. This is very important as barely any mobile phones have enough storage space required for the full blockchain. Mobile wallets are also considered hotwallets, meaning they have an active connection to the internet. The mere fact of being 'online' allows for a number of attack vectors and as such should never be used to store large amounts. It is however not unsafe per se. Private keys are stored locally and encrypted. Some wallets keep backups of those encrypted private keys on a server of their own, and this is something to take note of, but not to fear. So without further ado, lets get to it. I focused on Android wallets, but many of the wallets mentioned here have iOS versions.

Wallet Breakdown

Samourai

Samourai focusses heavily on anonymity and obfuscation. Addresses are never used more than once. When making a transaction there is an obfuscation slider. Samourai has had SegWit enabled since October. Furthermore it offers a plethora of different features, too much to sum up here. If you are an advanced crypto-user you should definitely check out this wallet and their website which explains all of the different features. The UI takes a bit of getting used to though.

Breadwallet

Breadwallet is a very simple to use, straightforward app. The UI is slick and intuitive and in-app support to basic questions is very well incorporated. This could be a good wallet for a new person to the scene. The lack of advanced features will make this app not the go-to for more experienced users. It does however feature fingerprint authentication, which is cool, as well as BCH extraction. The lack of SegWit and complete absence of custom fee's is a problem though, especially since fees have gone up during the recent BTC spike. With only 2 fee options to choose from I simply can not recommend this wallet to people who are looking to make frequent transactions.

GreenAddress

When I first started with Greenaddress I didn't like the UI, I found it a bit clumsy. So definitely not user-friendly for a beginner. On the plus side it allows a choice of 2FA settings. Furthermore it has SegWit enabled and it has some advanced features like nLockTime transactions and it offers a service for instant transactions. This all feels very Lightning Network-y, which makes sense as GreenAddress is a part of Blockstream. Our friends in the other sub will most likely have something to say about this. I'll refrain from this and just say the following: this is an advanced wallet with promising features. If they clean up their UI a bit I could see myself using this without hesitation. The fact that they have MultiSig is a big plus as most mobile wallets do not have this functionality.

AirBitz

Unlike any other wallet I fired up at that point, this app did not prompt me with a 12- or 24-word seed. Instead it made me make an account, the regular username/password combo. After some research I found that these are not stored in a local database on their end. Which means that recovering your password in case of loss like with every other username/password login method we are so used to, is not possible. It is merely a different representation of an encryption key, allowing you access to your private keys. It features some interesting stuff though, NFC-compliant transactions and Bluetooth Low Energy (BLE) for example. Clearly this app is meant to be a bridge between users and merchants and has focus on making regular in-person transactions. Thus it mimics some non-crypto related payment apps that we have. Personally, I am not a fan, but I can appreciate the design philosophy and I would't be surprised if their design model worked very well in the future with the LN or with other crypto's that focus on small payments. As for the UI, it's fairly simple, yet horribly cluttered with partnered services. Good for non-techies maybe, but not for more experienced crypto-enthusiasts.

Electrum

Much like the desktop wallet I used years ago when I first started with Bitcoin, the mobile wallet is minimal. Straightforward and without fancy colors or UI. For those of us who have known the internet before Facebook, this app will feel strangely familiar. This is a classic example of a no-nonsense wallet with the features that really matter. SegWit and MultiSig enabled. A further lack of advanced options might be a turn-off for some users out there though. I did however find the option to spend coins from unconfirmed transactions. This could be very useful in case you want to cancel out a previously stuck or erroneous transaction and ensure it's never cleared. One downside to this wallet is the very primitive way of setting a custom fee. No guidelines, scrollwheel or info. Just a simple box in which to put your fee which won't help intermediate users, only experienced users.
Edit: sidenote on the SegWit implementation by Electrum http://www.crypto-economy.net/electrum-3-0-enables-bech32-segwit-addresses/?lang=en

CoPay

Of all the apps I've tried up to this point, CoPay had the best initializing phase, succinctly explaining risk and security. I can not imagine a better intro to a wallet for a first time bitcoiner. It being of a product of BitPay, of which I am personally not a fan, I have to admit though. This app looks clean, feels fast and is easy to use. It successfully demystified MultiSig functionality in its UI and partnered services are not obtrusive in the design. Downsides are lack of fee setting possibilities and SegWit. The latter I really do not understand given their main core of business. If it wasn't for those last two points, I would not see why not to recommend this wallet.

ArcBit

This app dissapointed me a bit. It starts out of the box, not mentioning any backup seeds or tutorial on the wallet itself or Bitcoin. It has no SegWit, no MultiSig, a lack of features and whilst a backup seed can still be requested from the settings, I feel it is of the utmost importance that such a security measure is not quickly overlooked. The lack of fee management tops it off. While this wallet works just fine and looks just fine, there are too many alternatives out there with better options and functionality for me to ever advise anyone to use this wallet.

CoinSpace

CoinSpace is one of those apps that could be really cool, but completely missed the boat on some other design choices. In-app ads unless you pay 1.6$ or something. Settings hidden behind a CoinSpace login screen. It features multiple tokens though with built in conversion through ShapeShift, which could have been awesome. But the excessive ads are just a big no-no. Lack of SegWit and limited fee options make this one of the least interesting wallets out there.

Simple Bitcoin Wallet

Simple Bitcoin is a very basic, barebone wallet. Feels like a one-man project. Almost no settings possible at all. There's much better out there.

Bither

I oddly liked Bither because of its design that reminded me of websites from the 2005-ish era using lots of gradients. Its one of those apps that you either like or you don't. The UI is not bad, but could be better, there's some functionality hidden in the settings, but not enough to satisfy. One very useful feature is built in BCH and BCG extraction. This is the first app I encountered with built in Bitcoin Gold access. It also has a separate tab with just market price information, which is really useful for the price ticker addicts among us. Furthermore it features Cold/Hot Storage View which allows you to monitor cold storage and with a nice graph shows you the distribution between Hot and Cold. Cool stuff. I would suggest to check it out, I'm sure some people will like and some won't. Do note, no SegWit. I would personally use this as a view-wallet only. Not as a spending wallet.

GreenBits

GreenBits is like the light version of GreenAddress. I tried looking for why one team would make 2 wallets but could not find a definitive answer asides from GreenBits being Android-native. And while some resources state MultiSig functionality and Tor through Orbot, I couldn't find those in this app. It does however sport SegWit and custom fees like GreenAddress. On the UI front I feel much more comfortable with this app though and I could see it being better received by average users. Looks like a good spending wallet without much extra.

Jaxx

Jaxx is a rather large wallet that supports many many many different coins with built in ShapeShift functionality. It did suffer from a hack earlier this year which is why this wallet has been discredited. I would however suggest looking into this one if you are invested in multiple different coins and regularly swap between them to get some financial edge. Lack of SegWit and fee options don't make this an ideal app for Bitcoin-only users.

Xapo

Xapo, known for its cold storage solutions was one of the apps I was eager to check out. Upon starting I however first had to verify through a text message, giving up my phone number, after which I was greeted by a 'Continue with Facebook or email' - screen. Upon choosing email, I was further asked to give up personal information. Nothing personal against these types of business models, but this is not what I am looking for in a mobile wallet. Centralization of personal information is quite in contrast with the decentralized and pseudonymous qualities of cryptocurrencies. This being the 13th wallet I've fired up tonight, I decided to give this one a pass.

Coinomi

Coinomi is very similar to Jaxx in the way that it supports a crapload of different currencies and in-app conversions between different tokens through ShapeShift and additionally Changelly. It does look quite a bit more straightforward though. A good alternative to Jaxx for those multicrypto traders among us. Unfortunately yet again not the best for straight Bitcoiners due to lack of SegWit. It has custom fees though, but much like Electrum, there's no real help here and it's just a manual input.

Mycelium

Mycelium has been my wallet app for a couple years now. Unfortunately the delay in SegWit adoption has me looking elsewhere and in succession writing this article. I really liked the recent addition of the fee scrollwheel, which is still the most detailed and succesful implementation of custom fees in any app I've seen. Having tried out many other apps at this point I can now see Mycelium, while not particulary user-unfriendly, could still very much improve its UI. It is however not a bad wallet, never crashed on me, always ran smooth through multiple updates. But let's not get sentimental here, it's a solid app, but its time for me and maybe you as well to try out something different ;-)

Conclusion

In this excruciatingly long article I've ran through a couple different wallet apps. One thing to learn is that not a single one of these is perfect and there's still room for improvement on many fronts. Which wallet holds your preference today depends largely on what you are looking for in a wallet. Do you want the cheapest transactions, then go for one of the SegWit enabled wallets. Do you like cool functionality, then check out Bither. Is anonymity of a concern to you then Samourai looks like the clear winner. More into multiple coins at once, then Coinomi or Jaxx is the way to go. And this is mobile wallets only, you have your desktop wallets, hardware wallets, cold storage solutions, paper wallets. But I'm all out of ink tonight!
I can't give you specific advice. In this world of cryptocurrencies we are in control of our own money. Being in control of your own money means being responsible for its security too. So make your own decision and due diligence.
Edit: Thanks everyone for the awesome responses. I've had some requests to further mention some important information regarding the wallets. I will write these down here as a memo to myself in the future, at which point I will review the state of mobile apps in greater detail once again. - Open Source or not - iOS version or not - Adding iOS only wallet apps

European Crypto Bank — Together, let’s build the Cryptobank of the Future

European Crypto Bank (ECB) is the culmination of 10 years of work and knowledge of financial markets, analysis and research.
It’s also the rapprochement of 3 companies : FORGUES GESTION France, FORGUES GESTION UK and WOOSPEAK and of 2 men : Olivier FORGUES and Mikael MISARD, as well as a complete team of financial, juridical, IT and experts managers. In 2008, Olivier Forgues (President of ECB) faced the Money Laundering Affair and the large-scale Tax Evasion, which was organized by UBS in France and then across Europe and the USA. As a former employee, ever since he wished to take time, as to apply the rules of diligence due, compliance and the applicable KYC, in accordance with the List of the Financial Risks, established by European Banks.

/r/BitcoinUK FAQ

/BitcoinUK FAQ

ArcaneWharf and I have put this post together quickly so that we have a resource which we can point newcomers towards in order to answer their frequently answered questions. This should serve as more of an overview or quick-start guide which is a jumping off point for beginners, rather than a comprehensive or complete guide.
This is a work-in-progress (i.e., definitely not perfect) which, as a community, we could expand and improve upon over time. If you have something to contribute (either to this or something more detailed), do comment in this thread or contact the mods (by sending a message to /BitcoinUK).

How can I learn more about bitcoin?

There are already some links in /BitcoinUK’s sidebar which should help you get started. If that’s not enough, check out:
We'd encourage you to at least understand the basics before making your first bitcoin purchase. There are tons of fantastic resources out there, so there’s no excuse for ignorance.

How do I buy bitcoin?

The answer depends on your priorities, as there tends to be a trade-off between more convenient, quicker options (which are more expensive) and less convenient, slower options (which are cheaper).

Getting started

Purchasing with a credit or debit card on Coinbase is the best starting point for beginners, as it offers a great user experience. There's a quick guide here, but you probably won't need it as the sign-up and purchase process is quite intuitive. If you're having issues with verification on Coinbase (or it's just taking too long), then you might want to check out the options described in the ‘high fees, but faster’ section below.
For subsequent purchases, check out the options described in the next two sections. Although the ‘no fees, but slower’ purchase route is popular and well recommended on /BitcoinUK, you shouldn’t automatically rule out the options described in the ‘high fees, but faster’ section.

No fees, but slower

The Revolut to GDAX route is frequently recommended in the /BitcoinUK community, as it eliminates fees and allows you to purchase bitcoin at the best possible price. Keep in mind that this route won’t work on weekends, as SEPA transfers only get pushed through during normal working hours (i.e., Monday AM till Friday PM). If you’re looking to purchase on weekends, then you’ll have to use the options described in the following section.
You can finds details about this purchase route in this text guide and this video guide
Summary of this process:
  1. Sign up for Coinbase and Revolut.
  2. Transfer GBP into your Revolut GBP account.
  3. Activate your EUR wallet
  4. Convert GBP to EUR in Revolut (FREE)
  5. Send EUR to Coinbase (FREE)
  6. Transfer EUR from Coinbase to GDAX (FREE)
  7. Buy bitcoin on the BTC/EUR market.

High fees, but faster

If you’re willing to pay a premium (i.e., pay above market-rate), then you can buy bitcoin quickly and conveniently with GBP UK bank transfers and debit/credit card purchases. The premium charged by these options is usually under 5%, but can extend beyond that during times of high demand and (positive) price volatility. Unlike the Revolut to GDAX route, these options also allow you to complete purchases on weekends.
Popular, frequently recommended options which are quick and convenient include:
Prices offered across these services vary day-to-day. For an overview of your options (and their relative competitiveness), you should check out BittyBot.co. This provides a full list of merchants and marketplaces available, ordered by price (cheapest first). You can also filter the output by payment method by typing it into the 'Search' box.
Some users may prefer to take this faster route if they are convinced the price of bitcoin will increase during the time it would take for a transfer to process from Revolut to GDAX (using the method detailed in the previous section). This can pay off, but be cautious. The volatility of bitcoin makes it a double-edged sword and its price could just as easily go down (drastically) as it could go up.

What's the best way to sell bitcoin?

You can sell bitcoins back to the majority of sites which you buy them from. As before, there's a trade-off between the quicker and slower options.
If you're looking to get a price which is closest to the market rate (and pay as few fees as possible), then you'll want to sell through an exchange like GDAX, exchanging your bitcoin for euros. GDAX is preferable when you're selling, as the price you'll get per bitcoin is higher. Essentially, just reverse the process detailed earlier in the FAQ (see this text guide or this video guide). Alternatively, check out this quick 3-minute video which walks you through the process.
Summary of this process:
  1. On GDAX, click ‘Withdraw Funds’ while in the EUBTC market
  2. Transfer to your Coinbase Account (FREE)
  3. Go to Coinbase > Accounts > Euro Wallet > Withdraw
  4. On Revolut, go into your Euro wallet > Top Up > Bank Transfer > EUR
  5. Note down the IBAN and BIC from Revolut, and enter them into Coinbase. Also include the amount you wish to withdraw.
  6. Withdraw funds into Revolut (15p charge)
  7. Once funds are in your Revolut EUR account, exchange from EUR to GBP (FREE)
  8. Go to GBP wallet > send funds. Add yourself as a beneficiary.
  9. Send the funds! (free)
If you sell bitcoin on Localbitcoins, Solidi, etc., you can get it sorted same-day (usually in less than an hour) with a transfer directly to your UK bank account in GBP. For that convenience, you'll usually get offered an exchange rate which is below the market-rate (usually up to 5%, but sometimes more). You are able to set your own sell orders on Localbitcoins or BitBargain (so you’ll be able to sell above market rate). However, we would not advise doing this as a newcomer.
Of course, you could always just withdraw directly from an exchange to your UK bank account. Again, you'll lose a percentage of your funds (>1%) in the foreign exchange conversion (from EUR to GBP) which your bank processes. Depending on the exchange rate charged by your bank, you might be better off selling through services which allow you to cash out in GBP instead.

How should I store bitcoin?

To simplify quite a broad topic, you essentially have two options: hot or cold.

Hot Wallet

A hot wallet is any wallet that is connected to the internet. Typically this will be in the form of a desktop program or a mobile app. Hot wallets rank high in convenience, but are not suitable for large holdings. They are extremely vulnerable to malware and backdoors, with hackers having strong financial incentives to target desktop wallets. Nevertheless, they are perfectly reasonable for storing small amounts of cryptocurrency.
Some popular options:

Cold Wallet

A cold wallet is a wallet that does not connect to the internet, and therefore cannot be affected by malware. There are multiple forms of cold storage, but beginners should first consider a hardware wallet.
A hardware wallet is a small, USB device where you can keep your cryptocurrency. They are secure since all of the information is stored on the device, so you could plug it in to a computer riddled with malware, and the malware would have no way of interacting with your wallet. These generally aren’t considered as secure as cold-storage wallets, but are much better than a hot-wallet. Usage just requires plugging the hardware wallet into your computer.
One drawback of a hardware wallet is the cost (£70-100). Although not a mandatory purchase, it is strongly recommended that you purchase a hardware wallet if you've accumulated (or plan to accumulate) coins which are worth more than between £500 - £1000.
Popular, well-recommended options include the:
Both are reputable and will serve you well. At the time of writing this, the Ledger is slightly cheaper and offers support for more cryptocurrencies. Unless you need the greater cryptocurrency support, the choice between them doesn’t really matter.
For an overview of the Ledger Nano S (with security recommendations and a small FAQ) see this post. For a tutorial on setting it up, check out this video.

More information

For a more information on different wallets, check out:
When setting up a wallet, it’s advisable to not record your mnemonic seed (which allows you to restore the wallet) on a digital device. Instead, it’s recommended to record it (clearly) on paper or card.

Why can't I just leave my bitcoin in the exchange?

When you buy bitcoin on an exchange (such as GDAX), the bitcoin is in your account but still belongs to the company who runs the exchange. Until you withdraw to your own wallet (as described above), the bitcoin is not truly yours. The bitcoin does not belong to you unless you own the private key. This is very important. Do not leave large amounts of cryptocurrency in an exchange.
Even if you trust that the company won’t run off with your bitcoin, an exchange is much more prone to getting hacked. Think about it from the perspective of a hacker: would you rather target a million individual users who only own a small amount of bitcoin each? Or would you target one exchange that you know is holding unfathomably large amounts of bitcoin? Don’t believe me?
If you're purchasing through Coinbase, you can withdraw cryptocurrencies through GDAX (same company) to your own wallet for free. Check out this how-to post for details.

Should I buy at £x price?

No one can tell you this. No one really knows what bitcoin will do in the future. Please do your own due diligence and consider dollar cost averaging.

What about Revolut’s in-app cryptocurrency offer?

Revolut is a mobile banking app that has recently announced support for cryptocurrencies. Note this section only refers to their service that allows you to buy cryptocurrencies within their application - not the process detailed above.
While more mainstream adoption is good, Revolut’s in-app cryptocurrency exchange - in its current state - does not allow you to withdraw your cryptocurrency from their application. This has all the same issues as leaving in exchange, as you don’t have the cryptocurrency in your own wallet.
Revolut’s in-app cryptocurrency exchange should be rolled out to all customers, if their FAQ is still accurate, by the 21st or 22nd December. Early access is available if you have premium or invite 3 friends who subsequently sign up and use their app. See here for more details.

How do UK taxes work with bitcoin?

Please note: This is not professional tax advice. Conduct your own research to verify this information and/or contact a professional tax advisor.
If you sell bitcoins at a higher price than you bought them for, or exchange them for something else (e.g., another cryptocurrency, and goods or services), you would be liable to pay capital gains tax. However, you have a capital gains allowance of £11,300 per year. If you generate profits from the sale or exchange of bitcoins which fall below this threshold, then no tax would be due. Additionally, no tax is due until you sell or exchange it for something else. You may also be able to reduce your capital gains liability by gifting cryptocurrencies to your partner so that they can take advantage of their capital gains allowance too (more details in this thread).
It appears unclear how you would be taxed in the UK in other circumstances: such as mining, working for cryptocurrency, or proof of stake rewards. As these rules develop, it’s advised to document everything you do with cryptocurrencies. When the taxman comes knocking, you’ll be grateful that you did.
IndeedHowlandReed has kindly putting together a more detailed guide about Bitcoin and UK tax. You can find part 1 here and part 2 here. If you have any questions not answered by their guide, post them in this thread (or upvote existing questions).

[uncensored-r/Bitcoin] Day 3: I will repost this guide daily until available solutions like SegWit & order batching are ...

The following post by Bastiat is being replicated because some comments within the post(but not the post itself) have been silently removed.
The original post can be found(in censored form) at this link:
np.reddit.com/ Bitcoin/comments/7ljpf5
The original post's content was as follows:
BACKGROUND
Subhan Nadeem has pointed out that:
If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
A few thousand bitcoin users from /Bitcoin switching to making their next transactions SegWit transactions will help take pressure off the network now, and together we can encourage exchanges/wallets to rapidly deploy SegWit for everyone ASAP. Let's make it happen. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed/ready exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin
IMPORTANT NOTE: The mempool is currently overflowing. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange

If I'm a HODLer, will it help to send my BTC to a SegWit address now?
  • No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unneccessary transactions for now.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
  • The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download Electrum v3.0.3 to generate a SegWit address.
    A transaction between two SegWit addresses is a SegWit transaction.
    A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction.
    A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a SegWit Tx if the sending address is a SegWit address.
    Source
What wallet are you using to "batch your sends"? And how can I do that?
  • Using Electrum, the "Tools" menu option: "Pay to many".
    Just enter your receive addresses and the amounts for each, and you can send multiple transactions for nearly the price of one.
Why doesn't the Core Wallet yet support SegWit?
  • The Core Wallet supports SegWit, but its GUI doesn't. The next update will likely have GUI support built-in
Why isn't a large exchange like Coinbase SegWit ready & deployed when much smaller exchanges already are? Why do they default to high fees? Where is the leadership there?

An in-depth overview of 15 different mobile Bitcoin wallets

Disclaimer: A lot of time went into writing this and more research than I anticipated. Errors are not just possible, they are certain. If you find any mistakes, please reach out to me and I'll edit. Furthermore I know I probably missed a couple apps, there are a lot out there. If I missed a big one, then again contact me and I'll consider adding it. If you are reading this in the future, note that these apps update regularly, anything mentioned here may have changed by the time you are reading it.

What is a mobile wallet?

A mobile Bitcoin wallet is an application for a mobile device which acts as a lightweight wallet and allows you to store, send and receive Bitcoin (or other cryptocurrencies and tokens). Mobile wallets use SPV (Simplified Payment Verification) to allow wallet functionality without having to download the whole blockchain. This is very important as barely any mobile phones have enough storage space required for the full blockchain. Mobile wallets are also considered hotwallets, meaning they have an active connection to the internet. The mere fact of being 'online' allows for a number of attack vectors and as such should never be used to store large amounts. It is however not unsafe per se. Private keys are stored locally and encrypted. Some wallets keep backups of those encrypted private keys on a server of their own, and this is something to take note of, but not to fear. So without further ado, lets get to it. I focused on Android wallets, but many of the wallets mentioned here have iOS versions.

Wallet Breakdown

Samourai

Samourai focusses heavily on anonymity and obfuscation. Addresses are never used more than once. When making a transaction there is an obfuscation slider. Samourai has had SegWit enabled since October. Furthermore it offers a plethora of different features, too much to sum up here. If you are an advanced crypto-user you should definitely check out this wallet and their website which explains all of the different features. The UI takes a bit of getting used to though.

Breadwallet

Breadwallet is a very simple to use, straightforward app. The UI is slick and intuitive and in-app support to basic questions is very well incorporated. This could be a good wallet for a new person to the scene. The lack of advanced features will make this app not the go-to for more experienced users. It does however feature fingerprint authentication, which is cool, as well as BCH extraction. The lack if SegWit and complete absence of custom fee's is a problem though, especially since fees have gone up during the recent BTC spike. With only 2 fee options to choose from I simply can not recommend this wallet to people who are looking to make frequent transactions.

GreenAddress

When I first started with Greenaddress I didn't like the UI, I found it a bit clumsy. So definitely not user-friendly for a beginner. On the plus side it allows a choice of 2FA settings. Furthermore it has SegWit enabled and it has some advanced features like nLockTime transactions and it offers a service for instant transactions. This all feels very Lightning Network-y, which makes sense as GreenAddress is a part of Blockstream. Our friends in the other sub will most likely have something to say about this. I'll refrain from this and just say the following: this is an advanced wallet with promising features. If they clean up their UI a bit I could see myself using this without hesitation. The fact that they have MultiSig is a big plus as most mobile wallets do not have this functionality.

AirBitz

Unlike any other wallet I fired up at that point, this app did not prompt me with a 12- or 24-word seed. Instead it made me make an account, the regular username/password combo. After some research I found that these are not stored in a local database on their end. Which means that recovering your password in case of loss like with every other username/password login method we are so used to, is not possible. It is merely a different representation of an encryption key, allowing you access to your private keys. It features some interesting stuff though, NFC-compliant transactions and Bluetooth Low Energy (BLE) for example. Clearly this app is meant to be a bridge between users and merchants and has focus on making regular in-person transactions. Thus it mimics some non-crypto related payment apps that we have. Personally, I am not a fan, but I can appreciate the design philosophy and I would't be surprised if their design model worked very well in the future with the LN or with other crypto's that focus on small payments. As for the UI, it's fairly simple, yet horribly cluttered with partnered services. Good for non-techies maybe, but not for more experienced crypto-enthusiasts.

Electrum

Much like the desktop wallet I used years ago when I first started with Bitcoin, the mobile wallet is minimal. Straightforward and without fancy colors or UI. For those of us who have known the internet before Facebook, this app will feel strangely familiar. This is a classic example of a no-nonsense wallet with the features that really matter. SegWit and MultiSig enabled. A further lack of advanced options might be a turn-off for some users out there though. I did however find the option to spend coins from unconfirmed transactions. This could be very useful in case you want to cancel out a previously stuck or erroneous transaction and ensure it's never cleared. One downside to this wallet is the very primitive way of setting a custom fee. No guidelines, scrollwheel or info. Just a simple box in which to put your fee which won't help intermediate users, only experienced users.

CoPay

Of all the apps I've tried up to this point, CoPay had the best initializing phase, succinctly explaining risk and security. I can not imagine a better intro to a wallet for a first time bitcoiner. It being of a product of BitPay, of which I am personally not a fan, I have to admit though. This app looks clean, feels fast and is easy to use. It successfully demystified MultiSig functionality in its UI and partnered services are not obtrusive in the design. Downsides are lack of fee setting possibilities and SegWit. The latter I really do not understand given their main core of business. If it wasn't for those last two points, I would not see why not to recommend this wallet.

ArcBit

This app dissapointed me a bit. It starts out of the box, not mentioning any backup seeds or tutorial on the wallet itself or Bitcoin. It has no SegWit, no MultiSig, a lack of features and whilst a backup seed can still be requested from the settings, I feel it is of the utmost importance that such a security measure is not quickly overlooked. The lack of fee management tops it off. While this wallet works just fine and looks just fine, there are too many alternatives out there with better options and functionality for me to ever advise anyone to use this wallet.

CoinSpace

CoinSpace is one of those apps that could be really cool, but completely missed the boat on some other design choices. In-app ads unless you pay 1.6$ or something. Settings hidden behind a CoinSpace login screen. It features multiple tokens though with built in conversion through ShapeShift, which could have been awesome. But the excessive ads are just a big no-no. Lack of SegWit and limited fee options make this one of the least interesting wallets out there.

Simple Bitcoin Wallet

Simple Bitcoin is a very basic, barebone wallet. Feels like a one-man project. Almost no settings possible at all. There's much better out there.

Bither

I oddly liked Bither because of its design that reminded me of websites from the 2005-ish era using lots of gradients. Its one of those apps that you either like or you don't. The UI is not bad, but could be better, there's some functionality hidden in the settings, but not enough to satisfy. One very useful feature is built in BCH and BCG extraction. This is the first app I encountered with built in Bitcoin Gold access. It also has a separate tab with just market price information, which is really useful for the price ticker addicts among us. Furthermore it features Cold/Hot Storage View which allows you to monitor cold storage and with a nice graph shows you the distribution between Hot and Cold. Cool stuff. I would suggest to check it out, I'm sure some people will like and some won't. Do note, no SegWit. I would personally use this as a view-wallet only. Not as a spending wallet.

GreenBits

GreenBits is like the light version of GreenAddress. I tried looking for why one team would make 2 wallets but could not find a definitive answer asides from GreenBits being Android-native. And while some resources state MultiSig functionality and Tor through Orbot, I couldn't find those in this app. It does however sport SegWit and custom fees like GreenAddress. On the UI front I feel much more comfortable with this app though and I could see it being better received by average users. Looks like a good spending wallet without much extra.

Jaxx

Jaxx is a rather large wallet that supports many many many different coins with built in ShapeShift functionality. It did suffer from a hack earlier this year which is why this wallet has been discredited. I would however suggest looking into this one if you are invested in multiple different coins and regularly swap between them to get some financial edge. Lack of SegWit and fee options don't make this an ideal app for Bitcoin-only users.

Xapo

Xapo, known for its cold storage solutions was one of the apps I was eager to check out. Upon starting I however first had to verify through a text message, giving up my phone number, after which I was greeted by a 'Continue with Facebook or email' - screen. Upon choosing email, I was further asked to give up personal information. Nothing personal against these types of business models, but this is not what I am looking for in a mobile wallet. Centralization of personal information is quite in contrast with the decentralized and pseudonymous qualities of cryptocurrencies. This being the 13th wallet I've fired up tonight, I decided to give this one a pass.

Coinomi

Coinomi is very similar to Jaxx in the way that it supports a crapload of different currencies and in-app conversions between different tokens through ShapeShift and additionally Changelly. It does look quite a bit more straightforward though. A good alternative to Jaxx for those multicrypto traders among us. Unfortunately yet again not the best for straight Bitcoiners due to lack of SegWit. It has custom fees though, but much like Electrum, there's no real help here and it's just a manual input.

Mycelium

Mycelium has been my wallet app for a couple years now. Unfortunately the delay in SegWit adoption has me looking elsewhere and in succession writing this article. I really liked the recent addition of the fee scrollwheel, which is still the most detailed and succesful implementation of custom fees in any app I've seen. Having tried out many other apps at this point I can now see Mycelium, while not particulary user-unfriendly, could still very much improve its UI. It is however not a bad wallet, never crashed on me, always ran smooth through multiple updates. But let's not get sentimental here, it's a solid app, but its time for me and maybe you as well to try out something different ;-)

Conclusion

In this excruciatingly long article I've ran through a couple different wallet apps. One thing to learn is that not a single one of these is perfect and there's still room for improvement on many fronts. Which wallet holds your preference today depends largely on what you are looking for in a wallet. Do you want the cheapest transactions, then go for one of the SegWit enabled wallets. Do you like cool functionality, then check out Bither. Is anonymity of a concern to you then Samourai looks like the clear winner. More into multiple coins at once, then Coinomi or Jaxx is the way to go. And this is mobile wallets only, you have your desktop wallets, hardware wallets, cold storage solutions, paper wallets. But I'm all out of ink tonight!
I can't give you specific advise. In this world of cryptocurrencies we are in control of our own money. Being in control of your own money means being responsible for its security too. So make your own decision and due diligence.
Edit: Thanks everyone for the awesome responses. I've had some requests to further mention some important information regarding the wallets. I will write these down here as a memo to myself in the future, at which point I will review the state of mobile apps in greater detail once again. - Open Source or not - iOS version or not - Adding iOS only wallet apps
