According to some sources, Binance was hacked just to hide the sale bitcoin of the Japanese (mt.gox) ( ~800k BTC ). If there are more information about the hacking exchange.Then, BTC breaking below 4xxx, maybe 2k5, I think the best way : u should to sell all your BTC, altcoin. All exchange will die. Thats' the second mt.gox. ***Attention from now until 7/4/2018.
The Chinese exchange is not easy to hack. If so, it is deliberate......
I do not think China's security level is very high. Because developed countries in the world, such as the United States, Britain and Japan, have been hacked many times in some underground government websites. So why hackers can not penetrate into a small trading platform?
I think you have been thinking negatively about it. But bitcoin's price will probably drop to over $ 4k because its real value is not $ 10k as it currently is.
