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 wouldn't go that far. I mean, in the past few months, it may have gone down to around 6.2k dollars, but I think that that would be its lowest fall. I say that because there is usually a lowest point value that one asset may only allow, I think if it will fall to around 4k dollars, that would really give the market a big blow, since Bitcoin value is one factor that guides the market whether it will gain or not. And, I don't think that the many Bitcoin holders and users in the market would allow for Bitcoin to just go down like that, especially without a fight.
