He couldn't care less about anyone's opinion here, and it's not that he's missing out on a life changing opportunity by ignoring Bitcoin. The only thing you can blame him for is speaking out against something he sees no value in.
This old fart could make a fortune if he invest in bitcoin back in 2013 / 2014, and I think this is an indisputable fact. Instead of that he
urges people to stay away from bitcoin, calling this coin “a mirage”. His real problem is he does not see the value in bitcoin, and with his negative statements discourages many small and big investors to invest in bitcoin.
They consider him one of the most influential investor, and public follow him like a flock of sheep - so I blame him for talking about something he does not understand, and in doing so it does a great deal of damage for bitcoin.
