What for Elon Musk needs Bitcoins if he already launched his own rocket with Tesla on board?
He is not interested in richness, he has another mission. He is really genius guy.
He is not interested in being rich, but I'm sure that he loves free money to invest in his projects. I mean, spacecrafts are not free.
You know there is a wide chasm between counting on (or even expecting) bitcoins prise to rise to give one some free money if one doesn't have any, just a few bitcoins that were bought or mined when bitcoin was a hundred dollars a piece, and responsibly managing your financial empire if one is already wealthy beyond what we can imagine.
I think that Elon Musk is already in case 2 scenario and he just doesn't have to count on bitcoin price to rise.
