I wrote this a few months ago for a personal project and decided to open-source it. You can get all historical OHLC data (1min granularity) from Bitfinex (earliest markets start from 2013) which can be used to carry out further in-depth analysis of market trends or backtesting trading/arbitrage bots.

For convenience, I can also provide a snapshot of the DB just contact me (email in profile) and I'll upload it.

Also I did the same for kraken/bittrex and gdax. Let me know if this is useful and i'll open-source them too!
