Elon is a player who is hard to predict. But as Jack and Cathie are BTC supporters, I assume it is more likely to pump after the meeting.
I agree with you on this, the price of bitcoin has crept up after the conference due to the presence of Jack and Chatie, while Elon Muskn for now I think he has lost his credibility even if he says something positive/negative about bitcoin it will definitely not affect much to the market, because his hand has weakened. Bitcoin doesn't need Elon Musk, we just need true backers.
