Crypto will definitely be an option but remember Gold and silver are not replaceable by fiat or cryptos. I think Crypto will take time to go mainstream. Once it is mainstream then in time of crisis, it will probably make the crypto market go extremely bullish. Crypto is not the answer to all economic problems. It is tool like fiat currency, the difference is one is centralized, the other one is not.
