Many early Bitcoin/crypto people are either uneducated on logical fallacies or they are just hypocrites.

“I was right about Bitcoin, therefore you should listen to me on subject X” is the composition fallacy a.k.a. the “part-to-whole” fallacy.

Just because the tires are made of rubber, doesn’t mean the whole car is made of rubber.

I see this same logical fallacy committed by religious dogmatists, racists, Democrats, Republicans, etc.
