Elon Musk is a smart person and has many ways to make what he manages to get a big profit. Elon Musk also invests heavily in BTC, Maybe with the announcement Elon Musk wants big investors to enter this investment. Thus, it will indirectly increase the price of BTC, and will also increase the productivity of the Tesla car company. But I believe buying Tesla with BTC will remain difficult, because the price of BTC is constantly changing, there will definitely be many changes in the calculation later here.
