So Nigeria has been destroying its currency. Shockingly, some people didn't actually want the little savings they had completely annihilated, and they weren't allowed to buy actual US dollars, so they bought stablecoins pegged to US dollars. I'm mostly anti-crypto but this is the exact situation where it provides a benefit. The government has garbage monetary policy which it enforces by trampling on peoples rights, all in the service of transferring wealth from the poor to the rich. Stablecoin access can't fix all of that, but it's better than nothing.
