I highly recommend bitfinex exchanges for crypto trading, because one of the exchanges has real volume. I used to trade on bitfinex
often because the display is very good and the features are very easy to use. But lately this is more convenient trading in binance,
does not mean bitfinex is bad. But this is just a matter of taste, if there are traders who have never traded on bitfinex I suggest to try it.
Because it will definitely feel something different compared other trading exchanges.
Sure, bitfiniex has not really done anything that will make us to doubt them except this their issue of tether than I am not very much comfortable with which I think they are using it to manipulate the market but I cannot really judge them based on what I am not so sure of, so they still remain one of the greatest exchange till they are proven otherwise, but I will prefer to stick with binance.
Aside from the issue of hacking that happened to them the last time which they too never expected anything of such. In term of great platform and a smooth-running operation, they remain the best and they also have one of the best tokens that anyone can invest in the market for now. There are still other great exchanges like kucoin, okex and many more that tends to want to compete with bitfiniex.
