Unless it becomes practical to pay for something with cryptocurrencies (which for me should be the primary use case of any currency) they basically seem used by people who want to time buys and sells according to the current boom/bust or pump/dump cycle.
2017 marked a pivotal point where Bitcoin specifically abandoned catering to the brick and mortar and e-commerce use cases, and started focusing on large scale financial services. It was a frustrating development for sure, but people all over the world are using various smaller cryptocurrencies to buy groceries every day.
Cryptocurrencies might not be useful for you specifically, and that's fine. Maybe you're not one of the various under-served target demographics. Complaining about that though is a bit like complaining that Yen is useless because you live in the US and none of the businesses you frequent accept Japanese currency. It's undeniably a trillion dollar global economy that provides a massive amount of value to millions.
Hearing that crypto may not be for me is quite surprising. It is advertised to me all over the place and the various stereotypical "cryptobros" seem curiously keen on people like me buying into the ecosystem, and appear to be very generously interested in helping me go "to the moon" etc. I've no idea how you're doing those things with crypto. I guess you have to go pretty far out of your way to buy, for example, airfare with a cryptocurrency or make otherwise really inconvenient trade-offs. I guess you might be semi-forced to use it due to, for example, living in a country with a currency which is more unpredictable than BTC then I think that's more of an black mark against the local currency than it is a feather in BTC's cap...
