The attitude of Elon Musk seems to be as stupid as can be. Of course some will say that when he manipulates the markets with big announcement like Tesla will accept Bitcoin, then Tesla will temporary stop accepting them, and soon Spacex will accept Bitcoin, this seems like a kid playing in a sandbox with friends.
However, this also enlight how crypto can be manipulated and needs some kind of control from the government.
If you are following the drama related to his market manipulation it is not restricted to the cryptocurrency market, for years he is doing the same in the stock market where some of his tweets will make and some will break the market and it is going on for years and he is aware of his market influence.
I think you are assuming too much here and if he is controlling the Twitter handle he has the power to influence the market and there is nothing that can be done against that.
What surprised me is that the correction in the
BTCitcoin market boosted the stock exchanges which means the money is flowing out from one market to another.
