Elon Musk being a businessman tried to make money out of his investments. He played the game and succeeded with his influence over the market. But we can't blame anyone, though it got into the market as a memecoin then onwards there is continued progress and more acceptance. The recent being the addition of Shiba Inu on 1800 Bitcoin ATM located around 31 States by Bank of America which is a registered entity of FinCEN.
We can. I do not support the idea that it is the investors themselves who are to blame for the fact that they have come to trust the speeches of Ilon Musk. It is also Musk's own fault, because he is a media and public figure, and he should be well aware of the effect of his statements. If someone influential suddenly says that he is disappointed in bitcoin and the price will go down, it is not to say that it is nobody's fault, you should have just not listened to this person.
Media personalities shouldn't abuse their influence on the masses and think about making money on the community, for this they sometimes go to jail, if it were the stock market.
