The due diligence stops the fraud that is rampant in crypto. It doesn't change the incentive structure of hype-over-substance though.

So long as you aren't (caught) overtly lying about the startup, all hype is fair game. Sam Altman can spout his ridiculous claims until the sun explodes.

The reason I left the security fraud part of the quote in is that the line is entirely demarked by what the SEC will enforce, not what's actually illegal according to the law or not. (And under the current admin, the SEC isn't gonna do shit.) There are a lot of tech startups doing securities fraud that'd get them hit by the regulators in any other part of the west.
