As you know new exchanges launching every day, you should not join every exchange and that exchange have a good ranking in coinmarketcap that should be joined, I have a bad experience with HITBTC, don't join this exchange because of freezing accounts.
I am not boasting, I have never had any bad experience with exchange ever since I joined the cryptocurrency market, and even down to my local exchange, I am also very picky about them and I try as much as possible to go for the best of them after making my research.
Before Binance was launched, I started using Polenix, but before Polenix started having the issue they had then which would have made me have bad experience, I already switched to Binance, and I must say that ever since I have been suing Binance exchange, I have never for once had issue and even when they were hacked then, it didnt affect me, although I was just amongst the lucky one.
Before Binance would have issue, I would have simply found another reliable exchange because I am not happy with the things that I have been hearing of them lately.
