Do you think Elon Musk is one of those who will push the price of bitcoin up to reach 100k$ each when the bull run comes?
Whether Elon musk supports bitcoin or not, whether he opposes bitcoin or not, whether he hodl his bitcoin or not, whether he sell all his bitcoin or not, whether tesla accept bitcoin or not, he has no effect on bitcoin in the long term.
Bitcoin can reach 100,000 dollars regardless of what Elonmusk do with his bitcoin.
Elon musk could do some manipulations in the market with his tweets. But I doubt his tweets has any more effect on bitcoin and I don't think he can affect the market even in short term.
