There has been significant growth of crypto as currency, particularly in the developing world with use of USD pegged stablecoins. It remains the only practical solution to make online transactions privately or when alternatives have been censored, potential pitfalls notwithstanding.

Centralized control is a threat, but it's one that is taken seriously, and by practical metrics crypto has been largely successful in defending its integrity here. Other related values measures worth looking at are credible neutrality, permissionlessness, and trustlessness, also basically areas it continues to succeed. You submit a valid transaction to a major blockchain, it's getting included, even if powerful people would rather it wasn't. Transactions that are illegal as per US sanctions are treated more or less equally to any other. Miners and stakers are not taking control of the money printer dial for their own enrichment. And there's reason to think this will continue, because in a lot of ways control is a liability, and giving it up is valuable; "CEO of Bitcoin" is not a sane title to aspire to because it would make you the responsible party and valid target for all sorts of legal threats and obligations, and just having it would destroy the value of what you control.

That said, as a means for the economic salvation of the median person like OP seems to be talking about, it was never going to do that on its own, no one who thinks honestly about it would promise that, and anyone who did is full of shit. It's just a new type of p2p money with some cool properties, that obviously isn't going to be enough to fix the mess that is the world's economic and political systems.
