Beginner project using YFinance - need help!

Hey all,
I'm fairly novice at Python, but have started to (attempt to) write useful programs. So far I've put one together that traverses a folder list and checks for a particular folder and either adds it if it isn't there, or renames it if it is labelled incorrectly.
I have recently almost finished my 2nd project. It's a data extractor that calculates percentage returns of most of the world's major stock market indices over a user-selected time period, using the YFinance library.
I've managed to capture and address all errors except for a ValueError to do with the datetime module. It will only come up if the user enters an incorrect date (e.g. the 31st of February) and causes the program to crash.
You will see in the While loop for the 'end date' field, I've tried adding the ValueError statement here (I've also tried other places in the code as well including under the loop that reads the dictionary of stock indices) but each time a wrong date format is entered, the error appears.
What I need help with is:
I've been reading up on datetime for much of the weekend but still haven't made any progress with it. I'm sure it's a relatively simple fix, but I am requesting help from those who are much more skilled than I.
Also if anyone notices any redundant info in the code, please don't hesitate to inform me!
Thanks in advance for your help!!

Best ways to buy Bitcoin in Japan?

I have purchased Bitcoin (and other crypto) before on Australian and Chinese exchanges, as well as LocalBitcoins in the past, but have never bought any in Japan. Was wondering what people's recommendations for a local exchange/wallet are? Looking for something FSA-approved and low fees.
I hear Bitflyer thrown around a lot, does anyone have any experience with that? I also see Rakuten has opened something called Rakuten Wallet but never heard of anyone using it.
Extra question in case anyone knows: If I buy Bitcoin in Japan, but sent the Bitcoin to an Australian exchange and then sold it later on the Australian exchange, how would tax be calculated? I assume I would need to record the equivalent AUD price when I bought it (despite having purchased in yen), and then calculate if there is a capital gain when I sold later in AUD. But do I pay tax to Japan or Australia in this case?

Tax Megathread

DISCLAIMER

The purpose of this post is to provide crypto-currency investors and traders with a basic understanding of the laws and prinipals regarding tax treatment for crypto-currency in Australia (including but no limited to Bitcoin) as it applies to individuals, not businesses.
At this point in time, this post does not attempt to explain tax treatment for businesses, or when trading in bitcoin is and is not classified as a business.
This post is a work in progress and will be updated and improved on an ongoing basis.
The Author(s) of this post are not tax accountants. Any advice given and/or any facts presented are based solely on our personal understanding of the rules and determinations made by the ATO and do not constitute financial advice. Please feel free to message any of the moderator team should you wish to dispute any of the facts or wording listed here. Please also feel free to offer suggestions and/or improvements that can be made in the comment section.
When in doubt, you should always seek professional advice from a tax accountant.

Captial Gains Tax

First and foremost, lets look at this exerpt from the ATO brief titled "Tax treatment of crypto-currencies in Australia" [1]
Transacting with bitcoin is akin to a barter arrangement, with similar tax consequences. Our view is that bitcoin is neither money nor a foreign currency, and the supply of bitcoin is not a financial supply for goods and services tax (GST) purposes. Bitcoin is, however, an asset for capital gains tax (CGT) purposes.
So this tells us two things.
1) Crypto-currencies are treated as assets for captial gains tax (CGT) purposes.
2) Crypto-currency trasnactions are treated as barter arrangements, with similar tax consequences.
Calculating capital gains tax (CGT) for your investments may sound daunting, but it is really very easy.
If you sell a capital asset, such as real estate or shares (or in our case, crypto-currencies), you usually make a capital gain or a capital loss. This is the difference between what it cost you to acquire the asset and what you receive when you dispose of it.[2]
You need to report capital gains and losses in your income tax return and pay tax on your capital gains. Although it's referred to as capital gains tax (CGT), this is actually part of your income tax, not a separate tax.[2] This means that the amount of CGT you pay will depend on your own marginal tax rate.
When you sell or otherwise dispose of an asset, it's called a capital gains tax (CGT) event. This is the point at which you make a capital gain or loss.[2]
Lets work through an example; Alice purchased 1BTC at a price of $6000 AUD per BTC in Janurary of 2016. Over the ourse of the year, the price of Bitcoin increased to $10000 AUD. Alice then sold 0.5BTC in December 2017 at a price of $10000 per BTC. Therefore the total amount gained from the sale was $5000. It is at this point in time that a CGT event is generated. Alice must now calucalte the profit for this CGT event so that she may declare it on her 2017/2018 tax return (As this is financial year that the CGT event occured).
The first step is to calculate the cost base for the 0.5BTC that was sold. In our example this is easy, Alice originally paid $6000 for 1BTC, which gives us a cost base of $3000 for 0.5BTC. The amount Alice received from sale of the 0.5BTC was $5000, so she subtracts the cost base from the sale price ($5000 - $3000) which leaves her with $2000 profit. This is the amount that Alice will record on her 2017/2018 tax return as a Capital Gain.

Other considerations

There are a number of other considerations to make when calculating profit for a CGT event.
  • The ATO offer individuals a 50% discount on capital gains when the disposed asset has been held for a period of time that exceeds 12 months. The way to make this calculation is as follows; Subtract the cost base from the capital proceeds, deduct any capital losses, then reduce by the relevant discount percentage. (50% for individuals). So in our above example, Alice will only be taxed on a $1000 capital gain had she held the Bitcoin for > 12 months. [3]. Alice would still need to declare the full capital gain on her tax return, but she would select the 'discount' method when performing the calculation. [9].
  • Any incidental costs associated with purchasing, holding, moving, and/or disposing of an asset may also be deducted from the capital proceeds prior to calculating the capital gain. The ATO provide the following example [4]
    The following example (with values inserted) illustrates how to calculate a capital gain:
    Capital proceeds (sale price) $10,210
    Less Cost base:
    • Purchase price $6,000
    • Incidental costs of purchase (Brokerage fee and GST) $100
    • Incidental costs of sale (Brokerage fees and GST) $110 $6,210
    Capital gain $4,000
    Further details for calculating the cost base, and reduced cost base of an asset can be found here.
  • Any capital losses may be carried forward from previous tax years and used to offset capital gains (if any) in the current tax year. [8]
  • It's important to note that losses are applied to any gains before applying the CGT discount. So if you have a carried forward loss of $1,000 and make a gain eligible for the discount of $2,000, your net gain is ($2,000 - $1,000) * 50% = $500.

Bitcoin as a personal use asset

Where you use bitcoin to purchase goods or services for personal use or consumption, any capital gain or loss from disposal of the bitcoin will be disregarded (as a personal use asset) provided the cost of the bitcoin is $10,000 or less. [1]
Personal use assets are CGT assets, other than collectables, used or kept mainly for the personal use or enjoyment of you or your associates. [5]
Personal use assets include:
  • boats
  • furniture
  • electrical goods
  • household items
Bitcoin that is kept or used mainly to make purchases of items for personal use or consumption ordinarily will be kept or used mainly for personal use. Bitcoin that is kept or used mainly for the purpose of profit-making or investment, or to facilitate purchases or sales in the course of carrying on business is not used or kept mainly for personal use. [6]
The ATO have released a Ruling Compendium to accompany TD2014/25EC. One section of this compendium provides clarification on when bitcoin will be a personal use asset.[10] (Item 10)
Item 10 section 1 states the following:
A taxpayer who purchases bitcoin with the intention of holding onto them for a number of years so that they appreciate in value and the profit can be spent in their retirement, is using the bitcoin for investment or profit making purposes and the bitcoin is not a personal use asset.[10]
Further, Item 11 section 3 states the following:
All of the facts and circumstances regarding the acquisition, use and disposal of the bitcoin are relevant to determining whether the bitcoin are a personal use asset.[10]
I urge everyone to read the Compendium, specifically items 10 and 11. These clarifications mean that bitcoin cannot be disposed of as a 'personal use asset' if they were bought or held with the intention of making a profit.

Bitcoin barter arrangements & trading crypto pairs

Transacting with bitcoin is akin to a barter arrangement. [1]
In its simplest form, bartering involves the direct exchange of goods or services for other goods or services without reference to money or a money value. [7]
Early we discussed the fact that Bitcoin and other crypto-currencies are treated and assets, and not currencies. What this means is that whenever you acquire crypto-currency, you are acquiring an asset. This means that trading crypto pairs is essentially a barter arrangement involving the disposal of one asset and an acquisition of a different asset. By definition, this means that you generate a CGT event each and every time you trade a crypto pair. The ATO law regarding barter arrangements tells us that you must assign an AUD value to the disposed asset as well as the acquired asset at the time of the trade. You must then calculate your capital gain or loss using these values.
As a general rule when valuing the consideration arising from barter or countertrade transactions, the ATO will accept a fair market value as adequately reflecting the money value or arm's length value, as applicable. In most cases, the ATO will accept as a fair market value, the cash price which the taxpayer would normally have charged a stranger for the services or for the sale of the goods or property. [7]

Different Platforms for dApps and Smart-Contracts
While Ethereum is the most mature dApp framework with both the best developer tools, resources and community, there are other public blockchain platforms. Third generation blockchains are trying to solve Ethereum’s scaling and performance issues. Here is an overview of dApp platforms that can be worth looking into:
NEO - https://neo.org/ The second most mature dApp platform. NEO has better scalability and performance than Ethereum and has 1’000 TPS to ETH’s 15 by utilizing a dBFT consensus algorithm. While better infrastructure, NEO does not have the maturity of Ethereum’s developer tools, documentation and community.
A writeup on why a company chose to develop on NEO and not Ethereum: https://medium.com/orbismesh/why-we-chose-neo-over-ethereum-37fc9208ffa0
Cardano - https://www.cardano.org/en/home/ While still in alpha with a long and ambitious roadmap ahead of it, Cardano is one of the most anticipated dApp platforms out there. IOHK, the research and engineering company that maintains Cardano, has listed a lot of great resources and scientific papers that is worth looking into.

IOHK Scientific Papers - https://iohk.io/research/papers/
Stellar - https://www.stellar.org/ If moving value fast from one party to another by using smart-contracts is the goal, Stellar Lumens is your platform. Initially as an open-source fork from Ripple, Stellar has become one of the mature frameworks for financial applications. Stellar’s focus lies in interoperability with legacy financial systems and cheap/fast value transfer. It’s smart-contract capability is rather limited in comparison to Ethereum and HyperLedger, so take that in consideration.
Ripplewww.ripple.com Ripple and its close cousin, Stellar, is two of the most well-known cryptocurrencies and DLT frameworks meant for the financial sector. Ripple enables instant settlement between banks for international transactions.

Consensus Algorithms

[Proof of Work] - very short, cuz it's well-known.
[1] Bitcoin - to generate a new block miner must generate hash of the new block header that is in line with given requirements.
Others: Ethereum, Litecoin etc.
[Hybrid of PoW and PoS]
[2] Decred - hybrid of “proof of work” and “proof of stake”. Blocks are created about every 5 minutes. Nodes in the network looking for a solution with a known difficulty to create a block (PoW). Once the solution is found it is broadcast to the network. The network then verifies the solution. Stakeholders who have locked some DCR in return for a ticket* now have the chance to vote on the block (PoS). 5 tickets are chosen pseudo-randomly from the ticket pool and if at least 3 of 5 vote ‘yes’ the block is permanently added to the blockchain. Both miners and voters are compensated with DCR : PoS - 30% and PoW - 60% of about 30 new Decred issued with a block. * 1 ticket = ability to cast 1 vote. Stakeholders must wait an average of 28 days (8,192 blocks) to vote their tickets.
[Proof of Stake]
[3] Nxt - The more tokens are held by account, the greater chance that account will earn the right to generate a block. The total reward received as a result of block generation is the sum of the transaction fees located within the block. Three values are key to determining which account is eligible to generate a block, which account earns the right to generate a block, and which block is taken to be the authoritative one in times of conflict: base target value, target value and cumulative difficulty. Each block on the chain has a generation signature parameter. To participate in the block's forging process, an active account digitally signs the generation signature of the previous block with its own public key. This creates a 64-byte signature, which is then hashed using SHA256. The first 8 bytes of the resulting hash are converted to a number, referred to as the account hit. The hit is compared to the current target value(active balance). If the computed hit is lower than the target, then the next block can be generated.
[4] Peercoin (chain-based proof of stake) - coin age parameter. Hybrid PoW and PoS algorithm. The longer your Peercoins have been stationary in your account (to a maximum of 90 days), the more power (coin age) they have to mint a block. The act of minting a block requires the consumption of coin age value, and the network determines consensus by selecting the chain with the largest total consumed coin age. Reward - minting + 1% yearly.
[5] Reddcoin (Proof of stake Velocity) - quite similar to Peercoin, difference: not linear coin-aging function (new coins gain weight quickly, and old coins gain weight increasingly slowly) to encourage Nodes Activity. Node with most coin age weight have a bigger chance to create block. To create block Node should calculate right hash. Block reward - interest on the weighted age of coins/ 5% annual interest in PoSV phase.
[6] Ethereum (Casper) - uses modified BFT consensus. Blocks will be created using PoW. In the Casper Phase 1 implementation for Ethereum, the “proposal mechanism" is the existing proof of work chain, modified to have a greatly reduced block reward. Blocks will be validated by set of Validators. Block is finalised when 2/3 of validators voted for it (not the number of validators is counted, but their deposit size). Block creator rewarded with Block Reward + Transaction FEES.
[7] Lisk (Delegated Proof-of-stake) - Lisk stakeholders vote with vote transaction (the weight of the vote depends on the amount of Lisk the stakeholder possess) and choose 101 Delegates, who create all blocks in the blockchain. One delegate creates 1 block within 1 round (1 round contains 101 blocks) -> At the beginning of each round, each delegate is assigned a slot indicating their position in the block generation process -> Delegate includes up to 25 transactions into the block, signs it and broadcasts it to the network -> As >51% of available peers agreed that this block is acceptable to be created (Broadhash consensus), a new block is added to the blockchain. *Any account may become a delegate, but only accounts with the required stake (no info how much) are allowed to generate blocks. Block reward - minted Lisks and transaction fees (fees for all 101 blocks are collected firstly and then are divided between delegates). Blocks appears every 10 sec.
[8] Cardano (Ouroboros Proof of Stake) - Blocks(slots) are created by Slot Leaders. Slot Leaders for N Epoch are chosen during n-1 Epoch. Slot Leaders are elected from the group of ADA stakeholders who have enough stake. Election process consist of 3 phases: Commitment phase: each elector generates a random value (secret), signs it and commit as message to network (other electors) saved in to block. -> Reveal phase: Each elector sends special value to open a commitment, all this values (opening) are put into the block. -> Recovery phase: each elector verifies that commitments and openings match and extracts the secrets and forms a SEED (randomly generated bytes string based on secrets). All electors get the same SEED. -> Follow the Satoshi algorithm : Elector who have coin which corresponded to SEED become a SLOT LEADER and get a right to create a block. Slot Leader is rewarded with minted ADA and transactions Fee.
[9] Tezos (Proof Of Stake) - generic and self-amending crypto-ledger. At the beginning of each cycle (2048 blocks), a random seed is derived from numbers that block miners chose and committed to in the penultimate cycle, and revealed in the last. -> Using this random seed, a follow the coin strategy (similar to Follow The Satoshi) is used to allocate mining rights and signing rights to stakeholders for the next cycle*. -> Blocks are mined by a random stakeholder (the miner) and includes multiple signatures of the previous block provided by random stakeholders (the signers). Mining and signing both offer a small reward but also require making a one cycle safety deposit to be forfeited in the event of a double mining or double signing.
· the more coins (rolls) you have - the more your chance to be a minesigner.
[10] Tendermint (Byzantine Fault Tolerance) - A proposal is signed and published by the designated proposer at each round. The proposer is chosen by a deterministic and non-choking round robin selection algorithm that selects proposers in proportion to their voting power. The proposer create the block, that should be validated by >2/3 of Validators, as follow: Propose -> Prevote -> Precommit -> Commit. Proposer rewarded with Transaction FEES.
[11] Tron (Byzantine Fault Tolerance) - This blockhain is still on development stage. Consensus algorithm = PoS + BFT (similar to Tendermint): PoS algorithm chooses a node as Proposer, this node has the power to generate a block. -> Proposer broadcasts a block that it want to release. -> Block enters the Prevote stage. It takes >2/3 of nodes' confirmations to enter the next stage. -> As the block is prevoted, it enters Precommit stage and needs >2/3 of node's confirmation to go further. -> As >2/3 of nodes have precommited the block it's commited to the blockchain with height +1. New blocks appears every 15 sec.
[12] NEO (Delegated Byzantine Fault Tolerance) - Consensus nodes* are elected by NEO holders -> The Speaker is identified (based on algorithm) -> He broadcasts proposal to create block -> Each Delegate (other consensus nodes) validates proposal -> Each Delegate sends response to other Delegates -> Delegate reaches consensus after receiving 2/3 positive responses -> Each Delegate signs the block and publishes it-> Each Delegate receives a full block. Block reward 6 GAS distributed proportionally in accordance with the NEO holding ratio among NEO holders. Speaker rewarded with transaction fees (mostly 0). * Stake 1000 GAS to nominate yourself for Bookkeeping(Consensus Node)
[13] EOS (Delegated Proof of Stake) - those who hold tokens on a blockchain adopting the EOS.IO software may select* block producers through a continuous approval voting system and anyone may choose to participate in block production and will be given an opportunity to produce blocks proportional to the total votes they have received relative to all other producers. At the start of each round 21 unique block producers are chosen. The top 20 by total approval are automatically chosen every round and the last producer is chosen proportional to their number of votes relative to other producers. Block should be confirmed by 2/3 or more of elected Block producers. Block Producer rewarded with Block rewards. *the more EOS tokens a stakeholder owns, the greater their voting power
[The XRP Ledger Consensus Process]
[14] Ripple - Each node receives transaction from external applications -> Each Node forms public list of all valid (not included into last ledger (=block)) transactions aka (Candidate Set) -> Nodes merge its candidate set with UNLs(Unique Node List) candidate sets and vote on the veracity of all transactions (1st round of consensus) -> all transactions that received at least 50% votes are passed on the next round (many rounds may take place) -> final round of consensus requires that min 80% of Nodes UNL agreeing on transactions. It means that at least 80% of Validating nodes should have same Candidate SET of transactions -> after that each Validating node computes a new ledger (=block) with all transactions (with 80% UNL agreement) and calculate ledger hash, signs and broadcasts -> All Validating nodes compare their ledgers hash -> Nodes of the network recognize a ledger instance as validated when a 80% of the peers have signed and broadcast the same validation hash. -> Process repeats. Ledger creation process lasts 5 sec(?). Each transaction includes transaction fee (min 0,00001 XRP) which is destroyed. No block rewards.
[The Stellar consensus protocol]
[15] Stellar (Federated Byzantine Agreement) - quite similar to Ripple. Key difference - quorum slice.
[Proof of Burn]
[16] Slimcoin - to get the right to write blocks Node should “burn” amount of coins. The more coins Node “burns” more chances it has to create blocks (for long period) -> Nodes address gets a score called Effective Burnt Coins that determines chance to find blocks. Block creator rewarded with block rewards.
[Proof of Importance]
[17] NEM - Only accounts that have min 10k vested coins are eligible to harvest (create a block). Accounts with higher importance scores have higher probabilities of harvesting a block. The higher amount of vested coins, the higher the account’s Importance score. And the higher amount of transactions that satisfy following conditions: - transactions sum min 1k coins, - transactions made within last 30 days, - recipient have 10k vested coins too, - the higher account’s Important score. Harvester is rewarded with fees for the transactions in the block. A new block is created approx. every 65 sec.
[Proof of Devotion]
[18] Nebulas (Proof of Devotion + BFT) - quite similar to POI, the PoD selects the accounts with high influence. All accounts are ranked according to their liquidity and propagation (Nebulas Rank) -> Top-ranked accounts are selected -> Chosen accounts pay deposit and are qualified as the blocks Validators* -> Algorithm pseudo-randomly chooses block Proposer -> After a new block is proposed, Validators Set (each Validator is charged a deposit) participate in a round of BFT-Style voting to verify block (1. Prepare stage -> 2. Commit Stage. Validators should have > 2/3 of total deposits to validate Block) -> Block is added. Block rewards : each Validator rewarded with 1 NAS. *Validators Set is dynamic, changes in Set may occur after Epoch change.
[IOTA Algorithm]
[19] IOTA - uses DAG (Directed Acyclic Graph) instead of blockchain (TANGLE equal to Ledger). Graph consist of transactions (not blocks). To issue a new transaction Node must approve 2 random other Transactions (not confirmed). Each transaction should be validate n(?) times. By validating PAST(2) transactions whole Network achieves Consensus. in Order to issue transaction Node: 1. Sign transaction with private key 2. choose two other Transactions to validate based on MCMC(Markov chain Monte Carlo) algorithm, check if 2 transactions are valid (node will never approve conflicting transactions) 3. make some PoW(similar to HashCash). -> New Transaction broadcasted to Network. Node don’t receive reward or fee.
[PBFT + PoW]
[20] Yobicash - uses PBFT and also PoW. Nodes reach consensus on transactions by querying other nodes. A node asks its peers about the state of a transaction: if it is known or not, and if it is a doublespending transaction or not. As follow : Node receives new transaction -> Checks if valid -> queries all known nodes for missing transactions (check if already in DAG ) -> queries 2/3 nodes for doublepsending and possibility -> if everything is ok add to DAG. Reward - nodes receive transaction fees + minting coins.
[Proof of Space/Proof of Capacity]
[21] Filecoin (Power Fault Tolerance) - the probability that the network elects a miner(Leader) to create a new block (it is referred to as the voting power of the miner) is proportional to storage currently in use in relation to the rest of the network. Each node has Power - storage in use verified with Proof of Spacetime by nodes. Leaders extend the chain by creating a block and propagating it to the network. There can be an empty block (when no leader). A block is committed if the majority of the participants add their weight on the chain where the block belongs to, by extending the chain or by signing blocks. Block creator rewarded with Block reward + transaction fees.
[Proof of Elapsed Time (POET)]
[22] Hyperledger Sawtooth - Goal - to solve BFT Validating Nodes limitation. Works only with intel’s SGX. PoET uses a random leader election model or a lottery based election model based on SGX, where the protocol randomly selects the next leader to finalize the block. Every validator requests a wait time from an enclave (a trusted function). -> The validator with the shortest wait time for a particular transaction block is elected the leader. -> The BlockPublisher is responsible for creating candidate blocks to extend the current chain. He takes direction from the consensus algorithm for when to create a block and when to publish a block. He creates, Finalizes, Signs Block and broadcast it -> Block Validators check block -> Block is created on top of blockchain.
[23] Byteball (Delegated Byzantine Fault Tolerance) - only verified nodes are allowed to be Validation nodes (list of requirements https://github.com/byteball/byteball-witness). Users choose in transaction set of 12 Validating nodes. Validating nodes(Witnesses) receive transaction fees.
[24] Nano - uses DAG, PoW (HashCash). Nano uses a block-lattice structure. Each account has its own blockchain (account-chain) equivalent to the account’s transaction/balance history. To add transaction user should make some HashCash PoW -> When user creates transaction Send Block appears on his blockchain and Receive block appears on Recipients blockchain. -> Peers in View receive Block -> Peers verify block (Double spending and check if already in the ledger) -> Peers achieve consensus and add block. In case of Fork (when 2 or more signed blocks reference the same previous block): Nano network resolves forks via a balance-weighted voting system where representative nodes vote for the block they observe, as >50% of weighted votes received, consensus achieved and block is retained in the Node’s ledger (block that lose the vote is discarded).
[25] Holochain - uses distributed hash table (DHT). Instead of trying to manage global consensus for every change to a huge blockchain ledger, every participant has their own signed hash chain. In case of multi-party transaction, it is signed to each party's chain. Each party signs the exact same transaction with links to each of their previous chain entries. After data is signed to local chains, it is shared to a DHT where every neighbor node validate it. Any consensus algorithms can be built on top of Holochain.
[26] Komodo ('Delegated' Delayed Proof of Work (dPoW)) - end-to-end blockchain solutions. DPoW consensus mechanism does not recognize The Longest Chain Rule to resolve a conflict in the network, instead the dPoW looks to backups it inserted previously into the chosen PoW blockchain. The process of inserting backups of Komodo transactions into a secure PoW is “notarization.” Notarisation is performed by the elected Notary nodes. Roughly every ten minutes, the Notary nodes perform a special block hash mined on the Komodo blockchain and take note of the overall Komodo blockchain “height”. The notary nodes process this specifc block so that their signatures are cryptographically included within the content of the notarized data. There are sixty-four “Notary nodes” elected by a stake-weighted vote, where ownership of KMD represents stake in the election. They are a special type of blockchain miner, having certain features in their underlying code that enable them to maintain an effective and cost-efcient blockchain and they periodically receives the privilege to mine a block on “easy difculty.”

Of Wolves and Weasels - Day 45 - Breadth and Scope

Hey all! GoodShibe here!
Yesterday I spoke about those off doing great work on our behalf, taking the lead or pushing the boundaries of what Dogecoin can do.
I think today is a great chance for everyone to get a real sense of what's going on here - what a group of 65,000+ Shibes has and is accomplishing as we speak (err... type).
So, please, if I've forgotten anyone, don't feel bad -- especially if you're doing something in another sub -- just let me know in the comments and I'll add it to the list, okay?
Here we go!

Have I missed something? I'm sure I've missed something! I can keep going but I'm already running late for work (got carried away)! Post in the comments and I'll add as I have time over the course of the day :D)
It's 9:14AM EST and we're at 52.53% of DOGEs found. Our Global Hashrate is spiking from ~68 to ~89 Gigahashes per second but our Difficulty is still riding low at ~1027!
Go! Mine! Have fun!
As always, I appreciate your support!

I've been working on a bot for crypto subs like /r/bitcoin for a few days now. Say hello to crypto_bot!

Hey guys, I've been working on crypto_bot for some time now. It provides a bunch of features that I hope will enhance your experience on /bitcoin (and any other subreddit). You can call it by mentioning it in a comment. I started working on this a few days ago. I'm constantly adding new features and will update this post when I do, but if you're interested I'll post all updates and some tips at /crypto_bot. Please either comment here, message me, or post there if you'd like to report a bug, request a feature, or offer feedback. There's also one hidden command :)
You can call multiple commands in one comment. Here's a description of the commands you can use:

Market Data:

crypto_bot 
Responds with the USD price of one bitcoin from an average of six of the top bitcoin exchanges (BTC-E, Bitstamp, Bitfinex, Coinbase, Kraken, Cryptsy).
crypto_bot ticker 
Responds with the USD price of one bitcoin at seven exchanges (all of the ones listed above, plus LocalBitcoins). Also lists the average at the bottom.
crypto_bot [exchange] 
Responds with the USD price of one bitcoin from [exchange] (any of the seven listed above).
crypto_bot [litecoin|ltc|dogecoin|doge] 
Responds with the USD price of one litecoin, or the price of 1 doge and 1,000 doge.
crypto_bot litecoin|ltc [exchange] 
Responds with the USD price of one litecoin from BTC-E, Bitfinex, Kraken, or Cryptsy.
crypto_bot [currency] 
Responds with the price of one bitcoin in the specified currency. Available currencies (symbols): JPY, CNY, SGD, HKD, CAD, NZD, AUD, CLP, GBP, DKK, SEK, ISK, CHF, BRL, EUR, RUB, PLN, THB, KRW, TWD.

Information:

crypto_bot [about|info] [arg] 
Responds with a short description about [arg], as well as a link to an external site (Wikipedia, bitcoin.it, and some others) for more information. You can list multiple arguments and get a description for each. Available arguments: bitcoin, block chain, transaction, address, genesis, satoshi, mining, confirmation, coinbase, gox, cold wallet, hot wallet.
crypto_bot legal 
Responds with a chart about the legality of bitcoin in 40 countries, copied straight from Wikipedia.
crypto_bot [explain transaction delay|explain tx delay] 
Responds with an explanation of why transactions may take longer to confirm (the bot specifically discusses spam-transaction attacks in this command).

Network information/tools:

crypto_bot difficulty 
Responds with the current difficulty of the bitcoin network.
crypto_bot [height|number of blocks] 
Responds with the current height of the block chain.
crypto_bot retarget 
Responds with what block the difficulty will recalculate at, as well as how many blocks until the network reaches that block.
crypto_bot [unconfirmed transactions|unconfirmed tx] 
Responds with the current number of unconfirmed transactions.
crypto_bot [new address|generate address] 
Responds with a newly-generated public and private key. This is mainly to provide an explanation of what both look like, and contains a clear warning to not use or send bitcoins to the address.
crypto_bot blockinfo [height] 
Responds with information about block #[height], including its hash, time discovered, and number of transactions.
crypto_bot [address] 
Responds with information about [address], including its balance and number of transactions.
crypto_bot [transaction_id] 
Responds with information about [transaction_id], including what block it was included in, its size, and its inputs and outputs.

Calculators:

crypto_bot calc <# miningspeed> [#][w] [#][kwh] [#][difficulty] [hc$#] [$#] [#%] 
Responds with calculations and information about how a miner would do with the above data (mining calculator). The only required field is mining speed. Order of the arguments does not matter. Everything other than hashrate defaults to the following if not given: w (watts): 0, kwh ($kilowatt cost/hour): 0, difficulty: current network difficulty, hc$ (hardware cost): $0, $: current bitcoin price in usd (according to Coinbase), % (pool fee): 0. The calculator does not account for nor allow for input of the increase/decrease of difficulty over time, though I may add this feature soon. Working hashing speeds: h/s, kh/s, mh/s, gh/s, th/s, ph/s.
Example usage: "crypto_bot calc 30th/s 10w .12kwh hc$55 1.5%" (to make it easier to remember, th/s can also be inputted as ths). This calls the bot with a hashrate of 30 th/s, electricity usage of 10w, a cost of $.12 kWh, a hardware cost of $55, and a pool fee of 1.5%.
crypto_bot number of btc <$amount to convert> [bp$bitcoin price] 
Responds with the number of bitcoins you could buy with <$amount to convert>. If the comment specifies a [bp$bitcoin price], it calculates it with that exchange rate. Otherwise, it uses the rate from Coinbase.
Example usage: "crypto_bot $419.29 bp$180.32" This calculates how many bitcoins you can buy if you have $419.29 and the bitcoin exchange rate is $180.32.

Broadcasting

SignMessage! "" 
Signs a message in the bitcoin block chain in a transaction using OP_RETURN. The message must be less than 40 characters.
Example usage: "SignMessage! "Post messages in the block chain!""
I hope you find this bot useful! Again, if you have any questions or comments, please either comment on this post, message me, or post on /crypto_bot.
Update 1 (June 24, 2015, 17:35): The bot now responds with information if you post a link to a block, transaction, or address on Blockchain.info in a comment, even if you don't call it. For example, if I wrote "https://blockchain.info/block/0000000000000000126448be07fb1f82af19fbbf07dd7e07ebcd08d42c2660cb" in a comment, it would respond with information about block #362,377.
Update 2 (July 10, 2015, 1:59): The bot now has two additional commands: "unconfirmed transactions" (or "unconfirmed tx") and "explain transaction delay" (or "explain tx delay"). The first command responds with the number of unconfirmed transactions, and the second explains why transactions might take extra time to confirm.
Update 3 (August 24, 2015, 1:34): The bot now responds in a better way than before when transaction ids or addresses are posted. Before, it only responded when the transaction id or address was used in a link to Blockchain.info. Now the bot will respond whenever a transaction id or address is posted at all; a link to Blockchain.info is no longer necessary.
Update 4 (August 27, 2015, 3:00): The bot can now sign messages in the Bitcoin block chain using OP_RETURN.
