It's reasonable to ask just how useful a use case is. Credit cards seem, on balance, to be demonstrably better than crypto for payments; to my mind, by a very large margin. Crypto brings nothing for me as an upside, and is a bigger hassle otherwise.
It's totally reasonable to ask how useful something is for you. However, other people might have other answers to that question. For instance, if existing solutions suited everyone - why are zelle and venmo so popular? Hell, I zelle money between MY OWN accounts at different banks just cause its faster, cheaper and easier then the alternative ACH/Wire transfers.
Edit: Hmm - if I could zelle to my brokerage account I probably wouldn't have missed out on that AMAT I'm salty about. :-P
My focus was payments (newegg was the original example), and I was comparing credit cards to crypto.
But let me ask: why use zelle to move money between accounts? Why not crypto? Or let's say you're sending money to a friend to split a check or something; would you use crypto vs any of the other "cash" transfer mechanisms?
I don't think that existing financial systems can't and shouldn't be replaced with something better, but so far cryptocurrency ain't it. I should also say that I'm not particularly susceptible to the ideological arguments on its behalf, which seem to be a big bonus for many. Maybe it's just not for me.
My bank/brokerage doesn't take crypto. So Zelle is the next best thing given how slow and expensive wiretransfer/ACH is.
(Wasn't wire transfer supposed to be 'fast', it generally seems slower then ACH?). And yes, I do use crypto to send 'cash' to friends.
I do agree wholeheartedly with your statement crypto isn't ready 'for the masses' yet. For one thing, no coin can handle anywhere near the transactions Visa can. But I don't see that as a reason to vilify it, shut it down, or pretend that only criminals use it.
In HN vernacular, I see crypto's as 'startups' - some will pan out, the vast majority won't. Hopefully, each generation of coin will improve on the ones before it.
as for "just not for me" - I'm only putting beer money in. I think most of us that have been in it for a while are in that position. Certainly none of us are out mortgaging our houses. Being skeptical of the hype is a good thing. Maybe in a few years/generations crypto will be in a place that's more useful to you :-)
