I do not think that Elon Musk first raised a fuss about SHIB, and then, knowing that the price for it was deliberately inflated, expressed a desire to sell Tesla electric cars for SHIB. Most likely, these are rumors. I don't think Elon Musk is so stupid, but that he will act to the detriment of his Tesla company.
I am still in favor of normal promising projects, such as the Muzicoin.io project. Muzicoin is a technology created to develop the global phonographic market, with the concept of distributing cryptocurrency rewards through music and interactivity on the Muzi platform. The IEO of this project is currently being held on the Coinsbit exchange.
