Why did Bitcoin go down in value so fast?

the big drop in bitcoin is due to bad publicity, to banks, to governments.
also all this is part of a strategy for bitcoin to lower the price as low as possible and then buy.
and most millionaires and wealthy people are investing in bitcoin, if you are a person with many followers or someone important just you just say a simple rumor to cause damage in the market to buy or sell.
Maybe I'm wrong I'm just a simple mortal, but I think now is a good time to invest because bitcoin will soon rise
