Elon Musk is creating his influence in crypto right now, so there are some steps he is taking, to get into the BTC and ETH system is very unlikely for him, let alone affect BTC and ETH itself, the only opportunity available is in Dogecoin at the moment to create its influence.

Elon Musk has his reasons for doing things, the level of influence in the crypto world is what he's aiming for, it's in line with what he's doing. I've heard this once, If we have become millionaires, but there is no influence whatsoever in the crypto world, it will be considered unsuccessful. Perhaps this is the reason why Elon Musk wants to create his influence.
