 ## TODO
 - Test accurate valuation for non xUSDT pairs
 - Add support for mixing trading pairs. For example: ETHUSDT in conjunction with ETHBTC
 - Add more exchange export support
 - Add profit calculation for all trading pairs
 - UI with graphs to plot your profits over time
-- Add support for .csv binance export
