Currently, it's `'bitmex', 'binance', 'bithumb', 'bitfinex', 'okex', 'huobipro', 'bittrex', 'poloniex', 'kucoin', 'cryptopia'` (planned to include top 20, just fixed the message on home page)
Any plans to include the top decentralized exchanges? (https://etherscan.io/stat/dextracker)
You might want to only include US exchanges (poloniex, bittrex, coinbase pro + bitstamp.. maybe Kraken)
