He keeps saying it's retarded and for retards without even giving one argument for his point of view, i took a look in his channel and he's been talking shit about bitcoin for the last 4 to 5 months now, when the bitcoin was around 5k $ it's now 2.5 times more, seems to me he's the retard, he should be embarrassed,.
To be fair he was talking about Bitcoin for years, not months, and he was always consistent in his conviction... Whether his is right or wrong only time will tell.
