My theory is that after this outstanding grow to +800b as every more experienced trader already knew we will have same size correction and it happened  it trully looked like we lived it through but some authorities that already had huge accumulated huge chunks started to sell in order to create continued panic that combined wtih all those negative news about all the bans and mt goax made it even worse becouse of that as we may all see there is some kind of pattern for daily sell/buys that are always made by some whale to even manipulate it more in order to accumluate more i duobt there could be even more bad news after all those taxes and this should slowly start recover it might takes a while but i duobt it will take longer then 1-2months.

At first this article may sound stupid or crazy but the more time you let it sink the more logical it gets.
