crypto-arbitrage

This repo is to figure out if one can profit by doing following steps:

1. Convert 10,000 USD to Coin X in Exchange 1.
2. Transfer Coin X to Exchange 2.
3. Convert Coin X to Coin Y in Exchange 2.
4. Transfer Coin Y to Exchange 1.
5. Convert Coin Y back to USD in Exchange 1.

Notes: Trading fees, funding fees and slippage are already considered in the calculation.

Notes:

• Tickers are fetched by cctx (a great package for cryptocurrency data).
• Transaction time is neglected in this calculation.
• More profit can be achieved by lowering exchange trade fee (i.e. by a larger principal).

TODO / Posible improvement:

• Support more exchanges
• Consider transaction time
• (Test it in real life!)
• Find optimal principal USD amount for highest return
• Real-time monitor (websocket)
• Handle trading here
