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,.
Now now there is no need to say negative stuff about anyone just cause they dont share your beliefs. Now i agree with the fact that some of his posts do seem to have a anti bitcoin sentiment to them. Maybe he did jump into bitcoin when the price was rising every day and he tought he would make some seriuos trades. Then again maybe he just dont like bitcoin and what it stands for and he is a ethereum hardcore fan.
