I feel like crypto can't really 'go to zero' anymore

That is not even because I think, that crypto is the superior financial tech, but because the legacy financial market doesn't give a shit about young people. Most millenials will never own a house, 'high yield' - savings accounts fetch 0.5% interest if you're lucky, inflation is basically a tax for the non asset holding population and the internet educates more and more young people about finance. I feel like even the "you don't talk about money" sentiment slowly but surely goes away and the more people realise its rigged, the fewer people are willing to join the party.

Tl;dr: Crypto won't succeed because it's better, crypto will succeed because everything else is literal shit from a butt.
