Musk is a business man and what ever he is doing is targeted at increasing his fortune so I believe that musk is going into crypto for the purpose of increasing his wealth catching in on the potentials that crypto offer , musk is one person that understand and love crypto because ad an entrepreneur that he is he quickly spot an opportunity and seize it
Before he takes the next official step, he needs to repair his image. He get a lot of damage in the last few weeks. Tesla has sold less cars and the media has write it very negative. His work with trump was at the end also not good for elon musk. I think he will release a new product in the future and then push his image in the world. That will maybe happen in the background with cryptocurrencies.
