Growing in market cap doesn't necessarily means manipulation of price will decrease soon, like for example the recent elon musk who people consider as the saviour of modern world making a fuss regarding crypto, as much as I'm happy enough that elon really bring the price of bitcoin up, I must say that these kind of things look kinda like manipulation.
If by some tweet from a rich influental people alone could decide whether the market gonna be bearish or bullrun the crypto market as a whole isn't really manipulation free doesn't matter how much the market cap has been growing since the manipulator doesn't target the market cap and using their resource to manipulate it but the manipulator affect psychology of the people to make them behave as they like.
Elon musk we can consider him as one of the whales am I right. Those whales were the one's behind the manipulations. As I expected some of the big/small investors was waiting for the price roll back.
But I don't think that there is some bad news that could affect the price go down. The popularity of the rumored richest man on earth Elon musk, would still stand against in any bad news.
