What is more significant price wise? Bill Gates buying more BTC for his foundation (a guy from the technology area investing) or Mike Tyson opening his own ATM (a more mainstream celeb investing)?
Bill Gates of course, he moves millions, but don't understimate the power of Mike Tyson. He is not only one of the best ever in the sport of boxing, he is part of American culture and a legend, thanks to this now millions of people will be aware that at least Bitcoin exists, so this is indeed awesome news, a great publicity stunt for Bitcoin.
