Binance has no doubt, besides that I also use several other exchanges and I think that is pretty good, like kucoin, hotbit, livecoin etc. but you have to be careful lately some big exchanges have been hacked, nothing guarantees the security of these exchanges from hackers, it's wise to save your money on exchanges
And binance is the latest exchange that have issue with hacking, there's still few more exchange aside from what has been mentioned, but it's the traders task to keep reviewing the security and reputation of the said exchanges in order to choose properly.
