This year I have traded on several different exchanges. And most of all I liked working for finance. There are large volumes of trading and user-friendly interface.
Yes i also used a lot of exchanges, for example, binance, bitrex, bitfinex, ccex, and i most found then good and legid ,i never face any problem while trading there in these exchange, but still i would like to say that in these exchanges i still prefer to bittrex, which i found more convenience and easy to use for trading different crytpo currencies.
