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
Maybe when Binance got hacked it can warn people what not all big exchange have good security system. Wise to save money on exchange is good too and maybe what people said about better to save in our own wallet must be more get focused.
