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 know more details regarding Binance, mt.gox, 800k BTC ...etc.
however, the Bitcoin market reacted and poured the $ 1000 barrier as a stability point and $ 6,000 as a minimum barrier.
The collapse/crash is always more than 40% of the market price "from 12,000$ to 7200".
As long as there is no bad news such as a Bitcoin ban or high fees, its only strong corrections
