The only reason Binance is so popular is that they don't list scam projects. The projects listed at Binance are the best and help investors get profit. In addition, Binance's security is very good and we do not need to fear hackers
there's always possibility of being hacked even when they invested so much into security there's always a hole but what most people want is that exchange able to make sure their clients fund safe and if there's something bad happen due to their mistake they will reimburse, binance so far is quite good at that I must admit.
