Mr. Elon is a very popular man all because he is very successful, and he is not shy in promoting his name and the things he is doing to the rest of the world especially the insatiable media. I think he is deserving to be titled as the richest man of the world maybe for the rest of 2021, though the list can be shifting due to economic gains and losses. He is indeed a very crypto-friendly guy having published some positive comments on Bitcoin and even Dogecoin, however there is no verified report that he has invested a chunk of his wealth with cryptocurrency.
