I prefer the Kucoin's interface, binance is not fast enough for me, well, maybe it is because i have a shit computer, but binance's interface consumes a lot of RAM, and that is the only sad thing about it.
But yea, binance is much more better anyways.
I prefer the binance interface for trading, but you have to admit that the exchange kucoin does a very good job too, with some exclusive corners. I don't understand the KCS dump these last few months... He had climbed very fast and very high, but now I find the correction rather violent...
