LOL. Those scams generally don't ask for donations. They advertise themselves with something like "Elon Musk decides to giveaway bitcoin in celebration of SN10 landing". Then they'll have some explanation about how the most tech-savvy man wants you to "learn" bitcoin. So, as a proof, you need to send some BTC and Musk will send you double of that.

There generally are lot of supporting replies saying, "OMG, My life has changed. Thank you so much @elon"..

It is indeed funny that people still fall for these scams.
