Currently I'm making use of binance like you, cause it undoubtedly the best crypto exchange right now, I make use of binance cause there's enough liquidity, also many pairs and not just that, the user interface is pretty cool seems kinda easy to navigate around for a newbie, have never made use of Okex, Huobi and Gate.io, I have used kucoin its also a nice exchange, but binance is still the exchange I prefer trading on cause it has more liquidity.
