Thank you for the sober and measured response.

I must say though, that US fiat has cratered since being pulled off the gold standard around 1971, and the purchasing power is always declining.

It seems like some cryptos fill a similar niche gold and silver fills in the physical world. While any individual crypto could be a pump-and-dump , the basket of all cryptos represent a concept that I'm confident enough in to wager will retain utility for our foreseeable lifetimes.
