But you're not being a skeptic here, you're just gambling.
Skepticism considers the ways in which you assumptions could have plausible positive or negative outcomes.
I see the entirety of the DeFi "industry" being regulated to death considering how many of these protocols and DAOs behave exactly like securities or replicate existing legal structures; I see no reason that governments will not seek to regulate them the same way.
We can look at the claims of crypt enthusiasts as stores of value, which is coherent, for sure, but if we're willing to give it the benefit of doubt then we should consider other equally shaky technologies and tech scenes, which doesn't give me much hope by itself.
The place where crypto has, and will likely continue to show value, is in money laundering and tax and currency control evasion. There are all things that, while illegal, _definitely_ have value, so my lower bound here is the value of a digital instrument to bypass these controls, especially in countries in which such things are tightly regulated.
That's not an insignificant lower bound; it is at least as large as a big fraction of the remittance industry + shadow banking. It's just that it's really, really difficult to make an honest living in this industry.
