For any investments in cryptocurrency, the correct formula for getting rich is this:
"Buy now, hold for 3-5 years, oh look there's no fiat left to sell your crypto for. Spend crypto anywhere @ 100x value you paid for it."
Fiat is not gonna be dead in five years man, sorry to burst your bubble.
Radio isn't dead just because we have internet.
People still read books too.
Not saying it might not die completely someday,
but not in five years especially considering mass
Adoption hasn't even begun.
EDIT: And btw, I would LOVE to be wrong here!
