Your distrust of human nature has caused you to double-down on trusting human nature. Those elaborate systems to counter human nature are built on, get this, more human nature.

Well, it's only one coin, with one algorithm, and people are pricing that into its value. But show me a better system. Not even the USD has a 50-year guarantee. Not only are your dollars likely worth 10% of their current value in fifty years, but there's an even chance that something has wiped their value out completely.
You're just irrationally afraid of crypto risk and irrationally accepting of human risk.
> Why should I sign up
Oh, I see your issue... Don't worry, nobody wants your permission any more than they do with USD. You don't need to, and can't, do anything.
