All of them are the same to me, I have used the likes of binance, bybit, KuCoin, Mexc and even bitget but seriously I don’t actually see much of a difference between them all. Some of them are even frustrating with almost weekly app updates. My most preferred one was binance before but right now I think I have gotten used to Bybit because of their derivative and future trading and also because of my country’s restrictions of other top exchanges.
I occasionally use Mexc simply because of the availability of many pairs for trading, but to be sincere both their android and iOS applications aren’t too different, even in terms of UI/UX I don’t think there is much difference.
