I AM NOT AN ACCOUNTANT, AND I AM CERTIANLY NOT YOUR ACCOUNTANT.

USE AT YOUR OWN RISK.

Usage:

1. Get a Blocktrail API key.

2. Gather CSVs.

3. Instantiate a Bifocal object. CSVs are passed in by filepath. API keys are strings.

b = bifocal.Bifocal(addresses=None, polo_key=None,
             polo_secret=None, blocktrail_key=None,
             coinbase_csv=None, celery_csv=None)

4 .Results can be found in the results dictionary.

b.results['BTC']['FIFO']
b.results['SJCX']['LIFO']

Assumptions:

Exchanges only get deposits from the user.

Exchanges only give withdrawals to the user.

Goals:

• Accept cryptocurrency addresses as inputs
• Compile data about Bitcoin and other cryptocurrency buys and sells via block explorer APIs.
• Calculate holdings, gains and losses in USD using public price APIs.
• Provide spreadsheets detailing transactions and gains.
• Provide choice of FIFO vs LIFO

Supports: Bitcoin

Counterparty tokens traded against Bitcoin

Poloniex

Parsing Coinbase Reports

Parsing (modified) Celery histories

Unsolved problems:

Counterparty block explorer APIs only return the most recent 100 transactions for an address.

Todo:

More tests.
