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
Indeed I think because of government as you can remember last year China has been ban the exchanger and same for Korea. I guess we doesn't feel it yet before then as the 2018 arrive we are now experiencing the effect of this issue last year. And add more scammers that makes bitcoin notorious that's why facebook and google banned it.
