Now the attitude of various countries towards stablecoins is: if you can't beat them, join them.
It has also overturned many of my previous understandings. I originally thought the United States was the first country to accelerate the promotion of stablecoins, but in reality, the U.S. just didn't want to be left behind as it saw others issuing them and companies competing for them, so it had to follow suit.
The current situation is indeed quite interesting; regulation is not actually ahead of technology, but rather due to its ambiguity and lag, has provided ample space for stablecoins to grow.
