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 will suggest to you my friend go to coin market cap and look at the price of the bitcoin and other altcoin going to be good stability
i never imagine bitcoin dump in price value 400ok usd, i think you need to learn yourself to calm and patience to avoid panic do not listen to news making bad effect for your investment.
