Eventually, people won't give a fuck about what Elon says and Bitcoin will move on. I think Elon Musk situation and tweets vs market movements keep getting exaggerated by mainstream media. I personally don't feel his tweets move the Bitcoin price these days.
You're right, he's losing a lot more IRL followers than those who follow him online. And even I don't believe that it's him that's causing the selloff but the markets are going through the moments of pain just because there's too much FUD being added by China and USA that the investors are now more worried on their investments. I hope we don't see a market crash like we saw 2-3 years back or else investors will fly away and BTC will only become a pawn of those high end institutions who want to take it away from the hands of an average investor to make it their personal way of making money.
