Elon has been able to manipulate the market and even bitcoin in the past, but I doubt he can do it again with bitcoin when everyone realizes his manipulations. The only thing he can manipulate in this market may be Dogecoin.
Elon is like us an investor and he just makes predictions like us, there will be right and wrong, don't blindly believe what he says.
But I will agree with you one thing, the market doesn't move the way we expect, when we expect a bull run, it moves in the opposite direction.
One of the problems with a power like influence is that the more you use it to your advantage while at the same time you use it to put others at a disadvantage the less effective it will become, Elon had a tremendous amount of power when he first came to this market as people were happy that a person as wealthy and as famous as he is was willing to give attention to this market, but then he began to do all kind of things just to earn some money for himself at the expense of everyone else, and since then his influence has decreased a lot with only meme coins owners giving him any attention during these days.
