Seeing these statement I had to bring it up in Bitcoin discussion ,but at the same time every one has his entitlement or point of view..
Brace yourself for more future critics by him about Bitcoin.
I suggest not taking him seriously or if out of curiosity, you really want to know more about why he is always like that, search why he is skeptical about crypto as a whole. Then from there, decide to yourself if those pointers by him make sense.
From now on, you have to be used to seeing statements like that, not just by him but by other popular and famous people as well.
