This situation once again showed how unstable the cryptocurrency market is. The news, about possible hacking of the exchange in a matter of minutes, crashed the entire crypto-currency market. So, you always need to be prepared for such dangerous reversals.
As for VIA, I think that ill-wishers deliberately tried to discredit this coin.
Well it wasn't the Binance hack news that caused the cryptocurrency market to crash but the Bitcoin price going down. As you might know the alts are tied to Bitcoin so Bitcoin going down has the same effect on the alts.
