...rather than cash out in fiat, I'd prefer physical silver and gold.
I thought of that too, and I do still hold some Au/Ag from 'way back in the day before I understood bitcoin.
But realistically selling out crypto to fiat and then buying metal with the fiat, holding it while the crypto world does whatever, then after things settle down again selling the metal back to fiat and re-buying crypto would probably incur a pretty hard hit on all the percentages taken by your local coin shop or bullion dealer etc.
More-so than even in crypto currency, I think buying precious metals should be a one-time, buy & hold (bury it in the back yard, or "oh no! boating accident") kind of thing.
Selling out my crypto for stacking gold/silver would probably mean I'd never get back into the same amount of crypto again, or at least not until long after missing the boat on whenever the next big 10X gain is coming...
