That's right, if only Elon Musk made a shilling of coins like Bitcoin, then his reputation would definitely increase and I'm sure you'd like it too, because people already in the crypto space wouldn't be able to hate Bitcoin.
He could have become a hero if he chooses to hype Bitcoin but unfortunately, he chooses to hype a meme coin of all the coin in the market, it's a big surprise that he choose to hype a coin like DogeCoin he can still make big bucks if he picks Bitcoin over Dogecoin, now the community hates him for making a wrong decision in the eyes of investors.
