I don't think so, superiority should be rated based on simplicity coupled with usefulness and reliability.

If you own a gold or silver coin and it's in your hot little hand you can use it to exchange for something you need as long as the other party will accept your coin.

But with cryptos you have a long list of items that all need to be working before you can even use the coin. Is the power on? Is the internet working? Is the government exercising control over the internet, making the exchange of cryptos impossible?

The government can do the same thing with cryptos they did with paper money, just pass laws saying everyone has to use fed coins. These coins can be fabricated at will, there's no limit to how many coins they can create. But there's a limit to the number of gold or silver coins that can be minted.

I think you'll see what I'm talking about in the near future as services get unreliable. Just look at the grocery stores, a year ago if I told you that certain products wouldn't be available you'd laugh at me and say go to another store.
