I believe this is not a bad idea, not like dude who invested 1.5+ billion dollars of his companies money on bitcoin and start accepting bitcoin will suddenly have a change of heart and start talking negatively about bitcoin, that looks as unlikely as possible. Which is why I think if you could be the first one to get in and wait for it to go up, depending on the situation we could have a decent profit thanks to it. Not like it increases a lot each time, it increased like 3% this time, so it wasn't a big deal, so it is not a trick to get rich.
We will not be able to get such information in a timely manner that Tesla has sold its 1.5 billion bitcoins. And I admit that such a decision can be made to fix the profit from the sale of BTC, which exceeds the profit from the sale of cars at the moment for the past year. And after Elon Musk tweets that Tesla sold BTC, I'm sure the price of bitcoin will go down.
