the idea that silver/gold would become inherently not money but crypto would indicates zero understanding of what makes money money
nothing about cryptos is inherently undilutable - except possibly the hard stop on bitcoin.
but crypto as a class is exactly like fiat - from a different set of issuers.
having a unique self retained history of ownership does not give something value as money - its not as if its widescale forgery thats causing people to lose faith in
cryptos that represent a claim on money or a fungible asset could certainly become money - but its the claim on the money/asset that would make them worthwhile - not their encrypted nature however safe and transferrable
volatility itself isnt a preclusion from becoming valued as money.
ultimately its the certainty that the money - whatever form - will retain most of its value as a claim against other goods over a long time is the main determinant
give cryptos half a life time of having proven that store of value and it may start to become seen as that
give it a full lifetime and it may start being treated that way at an accounting level by banks etc
until then they are just funky trading cards - great ways to speculate for big gains in small timeframes - but not acceptable at an institutional level as a safe set and forget asset that is valued in the net stable funding ratio
not to be confused with hedge and investment funds that will accumulate to speculate - same as the other private trading card collectors
