Leave this guy alone, he's like 130 yrs old. I consider him a guy that earned his authority, but he's not in the league anymore
The guy deserves respect for what he has done in the investment industry, but this is not his turf or niche he is not young anymore to explore or he don't have the time and effort to do it, because of his age, Cryptocurrency and blockchain will go on and he is works and teaching, some Cryptocurrency investrors are also applying some of this teaching in Cryptocurrency.
