And just because most people here agree that anonymous internet users breathlessly shilling cryptocurrency get-rich-quick pyramid schemes here are scammers, doesn't mean it's groupthink. It's simply, objectively, and obviously true, and it's all the irrefutable evidence of scams and crimes like the subject of this discussion that cause most people here to believe the truth, not "groupthink".
It's not groupthink to believe 1+1=2, and casually dismiss anyone who says otherwise.
If you want to wag your accusatory "groupthink" finger at people causing actual tangible damage to the environment and economy, while lying, shilling, pumping and dumping, ripping people off, committing crimes, and laundering money with NFTs and cryptocurrency, then point it at the cryptocurrency shills parroting bullshit talking points. They're the ones all thinking and talking the same, and generating all the hype.
