If Binance was smooth and good for you why are you looking for an alternative? Anyway, the altcoin exchanges that are pretty okay based on my experience and are decently reputable are Huobi Global(HBG), OKEx, and probably Bittrex(though I haven't used it in a year). But as always, do your due diligence when it comes to any exchanges.
I want to say the same.If he do already have smooth experience with Binance then why he do still look for other exchange? Stick to it on where you do feel comfortable and suit out your needs.Answering up the question then i would go with Okex my next choice.
Definitely OP would want us suggest another crab exchange in form of advise, am in love with Binance and heard never had any issue with their platform. For those who have good access to Binance should marry what they have already known and trusted. Other exchanges should be avoided form now and, during the coming bull run many exchanges will be open for business but will disappear after some good funds hold on their exchange. We should be more careful with new exchanges.
