First of all, I want to note that someone always makes money at the exchange, and someone loses money. Otherwise, it does not work. I earn on arbitration, for me, conveniently, the rate on yobit is always higher than on Exmo, BitForex, or Binance. I agree, it is not very profitable to output BTC, but there are a lot of other currencies for this purpose. You can trade a lot of coins in pairs with BTC, moreover, almost all markets are live and active. Sometimes it is interesting to read the chat, right there you can write to the moderator. I can not say anything about technical support, as I have not been able to contact them or ask for help myself, in general, I recommend this exchange for trading.
