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.
He would really need up his head to be examined if he do really believes such thing 
Total FUD and same on most people do say on here, This is only a small exchange with have Millions been stolen but it doesnt mean it is the main cause of such nose dive price decrease of bitcoin.There are lots of factors actually why we do on dumping state but pointing out the main would really remain unanswered.
