This is confirmed FUD. That was some minor exchange that traded altcoins, even without fiat pairs. Check it's position on the market and daily volume. Do you believe that somebody stealing 20 million USD worth altcoins would cause a crash of an unrelated cryptocurrency (BTC) measured in billions? If you do, you need to have your head examined.
Bitcoin prices have fallen sharply in recent days and I am afraid that the market will fall into recession, you can see that bitcoin prices are constantly fluctuating and will be able to continue falling sharply in the coming days. It is very difficult to succeed commercially. The market is bearish in the long term so bitcoin prices may fall further and will touch the $ 4000 mark.
