I somewhat agree, not that they aren't ready for Bitcoin though, from what I can tell third world countries have more adoption of Bitcoin. And anything that would stop someone using Bitcoin is going to stop them using tether(lack of electricity etc.)

But you're right the people using tether would mostly adopt a different pegged coins if tether disappeared .

It'd be cool to see some "stablecoins" not based on USD, probably not something you're worried about for now but there's crypto pegged to gold, silver, carbon credits, other currencies, etc.
