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.
Yes it is FUD and it sure does work.
Looks like the weak hands are getting larger in population. Just a small trading site hacking can cause this lots of changes in the price.
I cannot say this is fluctuation anymore. That is way to far from just day trading. They cannot shake it for that much. It could be a whale is dying and started withdrawals or the FUD is working.
I dont care though. It is bitcoin. It will be back.
