Don't be surprised if Buffet is really holding Bitcoin. But you are correct in how move on some of that stuff.
Plot twist, buffet assembled the "Satoshi" team. No seriously though, I'm not surprised about 50 Cent, but buffet is a whole other level of investor. Buffet is considered the top institutional investor, bitcoin is a waste of his time based on what he does. 50 cent on the other hand, it's quite funny. His accounting would have to be extra bad to forget that he owns payments he has received.
