When you go outside of the nice countries, local money becomes worthless. Nobody wants it, they'd much rather have dollars instead. Stablecoins for the first time offer a reasonable way for the global poor to store value in dollars, or in the form of any relatively stable currency. Obviously this comes with all kinds of issues, but it's still better than the original situation where "savings" simply didn't exist exce…
The global poor already had ways to store value in dollars. They could simply exchange whatever meager savings they had into... real dollars! And they have been doing that for decades. I don't know whether anyone in the west really believes in this bullshit of cryptocurrencies that give the global poor options.
I really don't think I need to explain the obvious difference between physical US dollar notes and USDT.
I'll point out that in most of the world a $100 note is only worth $100 if it's in basically mint condition, the value falls rapidly as condition degrades.
