We do not suggest using yobit or hitbtc as that exchange will not be good for new people or traders. We prefer to use binance for trading as that exchange will be enough for our option to trade.
Yes, both Binance and Bittrex will be the best exchange for us, but Bittrex requires people to verify their account. So Binance will be enough for him to trade and he will have a big chance to profit.
I prefer to choose a Binance exchange because I am finding the best coin there and we are getting some good profit through Binance exchange, of course, everybody doesn't like based on their experience they will suggest different exchange, before sticking to exchange we should give it a trial.
