This is not true: you don't invest in something with 20% weekly swings to "maintain assets" against 1-3% inflation. You just don't.

Haha, yes if you're just a "weekly" investor. But for me who invested years ago, my assets begs to differ. Back then there were people I know personally that like you who also said that it's a bad idea to invest in crypto, I'm very glad I didn't listen to them haha. Now I just tell them it is not yet too late before global adoption.

If you think real inflation is 1-3% right now — when house prices are up 20% y/y — you may not be paying attention.
