If you pay close attention, you will noticed that Elon Musk seems to have deployed that method to cash out. Don't be surprise if he comes back again and accumulate Bitcoin citing one uncoherent reason for coming back... but then, he would have bought very low to sell high fee years from now. This guys are playing money game...
Yeah I think you have a point because I could remember on 13 may 2022 when Alon musk tweeted about Tesla plans to no longer accept Bitcoin payment immediately the Bitcoin price fell from $54,819 to $45,700, with that it provides an opportunity for him to enter the market to buy larger amounts of Bitcoin and sells as the price goes up, with that method I believe he makes a thousand and millions of dollars even on January 2021 he also Tweeted about doge coin and immediately the price went 300% uptrend in four hours before it starts dropping back, and he must have accumulated enough dogecoin before he tweeted so as to enable him sell on higher price.
