Bitcoin's first block dates back to January 2009, or 13 years. POS devices have existed since, at least, 2017, or five years. Despite that people are using crypto less as a currency today than they ever have. What are the next 8 years going to bring us that the past 13 haven't?
It seems like as time goes on crypto becomes less useful rather than more as a general utility for buying stuff. Most crypto "currencies" are also a not a great store of value currently.
Just for context, the Ukrainian Hryvnia has lost less value since the Russian invasion than bitcoin has lost today. A financial system more volatile than the economy of a country outmatched in a war with a superpower, is perhaps, not a system you want doing things that require stability.
