Bill gates so happen to be a supporter of bitcoin but why he is now saying that statements about it now, Buffet and Munger don't know how bitcoin and blockchain work, saying it is a worthless gold and a rat poison that may have a bad ending on the future? here we go again for trademarking the future, yep other people did the same bashing to the internet when it is starting look in the present they are using it what funny critics, they probably have bags of bitcoin hiding to their wallets.
