Hi!

Interesting project. Have you considered adding checks for triangular arbitrage opportunities? For example, coincheck.jp offers margin trading (so does okcoin.cn for that matter) meaning that the bot could work for a triangular arbitrage between JPY/BTC/USD or CNY/BTC/USD. Also opens up plenty more exchanges.

The only forseeable problem is that you'd have to find a reliable website to convert USD<->JPY/CNY for the initial deposit into the balance, but that shouldn't be a problem considering the wealth of money exchange platforms out there (OFX, TransferWise, etc.)

Anyway, seriously interesting venture and I'll keep checking back on this.
