This will probably bring a big pump and dump, I believe in long term BTC and not in such moves.
Agreed.
Well, just because he is the most influential people around the world. That is the power if you are the richest man on earth, you can influence people who follow you, and that brings a massive adoption of bitcoin. This will give a pump and dump with bitcoin price, as we can saw in the market, bitcoin was gained too much price increased. Perhaps just also because of Elon Musk dogecoin was increased too much and then at this moment it had a short correction. Indeed, more and more influencer will come to bitcoin will surely give awareness to people or potential big investors.
