Nope its because government are trying to minimize bitcoin which it can affect the prices of the market. Facebook and google are doing the ban as well and that can affect also the prices
I do not think that any of the ban story either from facebook nor google or even the bid to regulate by government is responsible for the drop of bitcoin. The price is dropping from my point of view because it is ranging. It is preparing to take a move. My advise is to hodl. Technically, this is not a time to sell.
