Or the crypto-bros know it's a scam, but want to be the scammer, and you're the heckler who is scaring away the new marks.

Which is potentially different than a mark who is in denial.

Though I'd guess a lot of people are arguably in both Venn diagram bubbles: they're consciously trying to be a scammer, but they're also useful idiots for the much bigger scammers (and quite possibly also fleeced on the way out).
