Not daily and I think that's the thing. I suppose when one says "cryptocurrency," there are a lot of possible ways one might use it. I agree that for a daily driver, very unlikely.

But "store of value" is still very much in play.

Crypto as a competitor to the 401k or "money in the mattress" strikes me as damn near inevitable.

There's no way in hell you could convince me to invest in anything as volatile as a pile of crypto coin for my retirement. My retirement account is for slow, gentle, growth, not for a rollercoaster that could end up at zero (within the realm of reasonability - yes, the entire stock market could disappear, but at that point we're not retiring, we're firing up the pursuit special and heading into the desert). This is why ETFs are so popular - they remove a lot of the volatility.

Why would I put my money under the mattress if I could pull it out tomorrow and it'd be worth half of what I thought it was? Yes, inflation is a thing for fiat, but that's nowhere near as volatile as crypto has and continues to be.

And a lot would say "good luck with that?"

Putting a lot in a retirement account today is of course less dumb than putting a lot in crypto.

But neither is guaranteed or certain; and quite a few people diversify their portfolios.

Today, I'd say you're an idiot if you do a lot of crypto -- but also, you're not too bright if you don't throw in a little.

As for tomorrow, who knows. The technology of crypto definitely works. The humans might also decide that this is worth something, or they might not.

Yes, agreed. If you can stomach the volatility over decade-long time spans, of course - which very many people can't.
