Sure, EM won’t have as much of an impact as before, but far from it he won’t continue to play his crypto games - the smell of the billions of dollars lurking there is simply irresistible - he will milk that cow to the last drop, no matter how much someone loved him or hated in the crypto world.
Expanding on this, Elon Musk isn't stupid, far from it actually. He knows that by putting out the statements hes put out, and seemingly looking to promote Doge as something great, would get heat from the community. I actually think that's one of the motivating factors behind it, the guy is a troll at heart, and has demonstrated this plenty of times before. Now, Elon Musk implying that he finds Doge as the cryptocurrency you need to invest in, seems to me like; a mockery. He's playing into the fact that Doge was created as a joke, and he's also making a joke out of the situation we have ourselves in.
Elon knows exactly what kind of influence he would have. He's a multi billionaire, considered a pioneer within his field, and is considered by many as a genius. The guy, knows he has incredible influence. He knows this, and this is in particularly poor taste, because of the semi recent exploitation of Twitter which resulted in many celebrities getting compromised, and promoting a "double your crypto" sort of tweet which resulted in a lot of people losing their money.
So, I do think his statements recently regarding Doge, and the way he's playing into it is in a little poor taste, but I don't for a minute believe he has sold his Bitcoin, and neither do I think Tesla have.
