Hi - Just one question - from a beginner. As i understand Coinigy has API's to trade with the most common exchanges. I wonder what you consider the top 3 or 5 Exchanges to have good variety of trading altcoins - including ripple, stellar, iota, cardano ... Any suggestions - beyond binance and bitfinex ?
Definitely Bittrex and Poloniex as serious ones. Then there is a BIG quality jump to the next exchanges (cryptopia, yobit, etc)
