I witnessed first-hand yesterday the mental gymnastics of a fellow who called out Bitcoin 10 YEARS ago as a ponzi/scam/lie/whatever double-down and vocalize frustration of his not being proved right by now because when it ultimately collapses it will mean way more people will be hurt, everyone will know they should have listened to him, those who did will thank him, etc etc...

Truly sad.

Bitcoin is indeed an IQ test but how do you deal with someone who is otherwise very intelligent but too proud to say they were wrong and unwilling to consider changing their mind? No convincing those types.
