Hey, man.
I use hitbit, bittrex, yobit and other exchanges. The size of these exchanges is very large, but the user experience is rather poor. This seems a bit trickier to use. I like more convenient communication.
Also tried some new exchanges
E.g:
Bibox (completely replicates binance, but overall is still relatively normal)
IDEX (decentralized trading, trading is particularly troublesome)
Bitpaction (current trading volume is too small, the market did not promote it)
At present, no exchange fee is the cheapest. Many times, this is the first time you have chosen an exchange, and then they stay there.
