"crypto" is not facing hack!
it is the shitty random exchanges out there with little security that are getting hacked. and it is not new, this has been happening all year last year during the rise so it is not the reason for the drops either.
additionally this is yet another proof that altcoin dumps can decrease the price of bitcoin as the money escapes through bitcoin. we know that the Bancor hack was a full altcoin loss (mostly they stole ETH if I am not mistaken) and the altcoins were getting dumped hard all this morning and bitcoin was still up, after some time of altcoin dump bitcoin came down as they cashed out through bitcoin.
