Big time investors are definitely manipulating the price to make money, and a lot of them are Chinese.
If you think this drop from $1100 to sub $800 wasn't partially manufactured, you're fooling yourself.
Smart, powerful people used existing events, spread FUD to further push prices down, and bought tons of cheap Bitcoin that weak investors sold off
Are you sure that the plunge was manufactured?
I'd rather say that the rally was on roids itself, and the collapse was inevitable. In fact, the manipulators didn't even need to do anything special to crash the price. After it had grown so much, it would crash under its own weight, so to speak, if supports got removed. The price growth was supported as long as it was profitable to support. As soon as it stopped being profitable, they crashed Bitcoin. Massive shorts by market makers (a handy euphemism for market manipulators) gave the price a good punch in the right direction

What people seem to not understand is that influence does not equal control.
It is mostly a matter of convention
