I was having this discussion with a friend recently, arguing over what the actual use cases are for crypto, and I came to a similar conclusion.
In terms of facilitating payments, cryptocurrencies are worse in almost every way I can think of compared to existing systems. They are (currently) slow, have high transaction fees, but most importantly the non-refundability of crypto transactions is a bug, not the feature crypto proponents suggest.
However, as a store of value (e.g. "digital gold"), I think crypto has real potential. There is a reason crypto is very popular in places with hyper-inflationary monetary systems like Venezuela and Iran. And compared to actual, physical gold, crypto is almost better in every way: it is much more easily transferred and stored, and the ledger means establishing "provenance" is not an issue. Yes, it's obviously currently extremely volatile, but it's not hard to imagine that volatility lessening over time.
