Personally if I were to send money globally I would send bitcoin but not everyone wants bitcoin because they can't spend it. My wife sends a donation to this church group in Africa quarterly that helps them buy food and supplies for churches and schools in remote areas. They use some African version of paypal to execute the transactions and it costs a lot. I think 20 dollars in fees for her to send 150 dollars. I wrote to them and suggested they take bitcoin over lightning but they said they were not interested because all of their suppliers only take the local currency or USD. That's a good example where a stablecoin could be super useful. If all the local vendors were able to take tether for instance, my wife could send the charity tether (over lightning soon) and they could pay their suppliers tether and not have to pay ridiculous fees to however many banking middlemen sit in the middle of the money transfer via the tradfi way.

Stablecoins bridge the gap between traditional finance and crypto, offering the benefits of digital currencies with reduced volatility. They serve as a safe haven during market turbulence and facilitate easier crypto transactions, appealing to those seeking a middle ground in the volatile crypto space.
