Your first approach should be a Wise multi-currency account.
Where Wise doesn't work the only thing that makes any sense are stablecoins from a proper issuer, like USDC (definitely not USDT). These are of course issued and controlled by centralized entities, making them antithetical to the very principles of crypto. They may as well be private scrip CBDCs.
Any decentralized/floating-rate coins are utter garbage for folks without access to meaningful banking systems in so-called third-world countries due to the volatility, embedded systemic leverage, high fees and potential long transaction times. These folks are the least able to stomach the 90% drawdowns (and 100% rug-pulls) we've seen market-wide. Frankly, I think the Turkish Lira has outperformed every major cryptocurrency for the last year.
What these people need are actual privacy-preserving CBDCs, of which there are exactly zero in the market.
Please put away the faux privilege defense. Folks of any level of privilege are able to comment meaningfully on the fitness of a technical system for purpose. Allow their arguments to stand on their own merits.
