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......
Theoretically, this is no longer possible, but given the fact that the cryptocurrency market today is one of the most unpredictable market in the world. So we can't know what will happen tomorrow.
But why do you think so? I think crypto has a great future, just society is not yet accustomed. But if you answer the basic question, I think maybe up to 5,000 but up to 4,000 is physically impossible.
