You're kind of repeating my point about non-equivalent of gold. Yes I agree in case of civilisation collapse btc will not be useful and gold may very well be.

But on the hyperinflation I disagree. Where did we see purchasing g power of btc to drop when currencies experience high inflation?

We have a plethora of opposite examples in various countries, and one very good global example. During covid when money printing was running full steam BTC skyrocketed and kept most of it's value.

There was a panic induced crash initially, but that recovered very quickly. Mind that sadly btc is used for speculation mostly, not as a currency so it is very prone to various panic and euphoria events. Still if you want to use it as a currency (to transfer or store wealth) independently of the banking system it is not bad.

Having said that I'd never put more than 1% of my worth in btc mainly because it's a bit archaic as far as crypto goes.
