Silver and gold are making records at the bullion stores, the us mint is running out of certain types of bars and coins, and this is just the beginning.
The nice thing about bitcoin, is that soon it will have less inflation than gold, and it can be sent anywhere in the world, and settled in less than a day, or even 10 minutes for larger/instantly for small txs on noncongested chains like cash.
Gold has to be weighed and tested for purity before it can settle and it cannot transfer instantly (at least not without a digital ledger), can be costly to use. Plus, digital currency makes virus transfer impossible.
The fed isn't close to coming up with any alternatives to fiat bills, or the dollar, ect. Even plastic can lead to the same types of exposure.
There is no choice but to accept digital currencies in the near future, as metals will be scarce, and fiat unusable!
