People expect that Bitcoin will be used as a hedge, but they forget that Bitcoin is highly volatile and immature, so those who want to preserve their money are more likely to use safer options like gold or foreign currency.
People who think bitcoin is some sort of hedge against either inflation or volatility are insane. You might as well just wipe your ass with $100 bills and flush them down the commode if you think that.
At this point I don't even think metals are all that good for hedging, since there are plenty of people who bought gold & silver in the past few years who are still underwater with their investment. On the other hand, metals have been less volatile than crypto and would protect you against a hyperinflation-type situation. Then again, I think if hyperinflation ever came around my local economy, anything I owned other than cash would look like a great hedge in comparison.
Turkey's economic crisis, like venezuela's, might be traced back to overprinting of fiat currency.
That's what worries me about the situation in the US. There hasn't been a lot of inflation in the past few years, but I suspect it's coming. The Treasury's printing presses must be smoking hot with all the new money they've been printing (and yes, I realize that money hasn't mostly been in the form of FRNs). It feels very much like waiting for the shoe to drop.
