Yea he has enough money but McAfee wasn't poor too. Maybe Elon is not doing it for money but for sure he is playing with people and their lives ... If I was about to make a bet i would say that he is doing that to boost his ego.
To tickle his self-esteem at the expense of people who spend weeks researching the market, doing TA, and investing taking know risk, while 1 tweet made as a joke destroys their returns. He knows that ... he don't give a fuck. In the moment when real interest rates are in ATL since 1980 and people are desperate to find good investment - he is doing it even harder for them. People who stay out of him are affected by his tweets, poeple who fallow him are baited into shitcoins "He does things for society" Yea sure XD
