Btc is most manipulated asset and shows that only those who are in power can do others whatever they want not by motivation of justice or order but only for their own gain.
I have to agree that Bitcoin can be manipulated in the sense that prices move up and down. FUDs, Whales, are of the most to be blamed but I don't think that we can say it was 100% manipulated. I know that some people will take advantage of their capabilities like whales to make change the market trend but people never take that seriously as they just think it was the part of the volatility which I believe was so.
And so why do people never stop buying and accumulating Bitcoin even they know such a thing? That was because manipulation has existed in all aspects of business, investment, and even in our life.
