Whether Elon musk supports bitcoin or not, whether he opposes bitcoin or not, whether he hodl his bitcoin or not, whether he sells all his bitcoin or not, whether Tesla accept bitcoin or not, he can't have any effect on bitcoin in the long term.
Bitcoin can reach 100,000 dollars regardless of what Elonmusk does with his bitcoin and what says about bitcoin.
Elon musk could do some manipulations in the market with his tweets in the past. But I doubt his tweets has any more effect on bitcoin and I don't think he can affect the market significantly even in the short term.
I am not saying bitcoin will reach 100,000 dollars and this is not a financial advice. Everything is possible.I have always thought about this. It's not same for just one person to control a huge project like Bitcoin. And it's not his fault though. It's the fault of everyone that wants him to talk on the next move of bitcoin. It's so sad if just one person can control the market that much.
