Maybe I'm dull, but I know what stablecoins do in the crypto world.

Then, I see various traditional finance people promoting stablecoins, and it feels like they are saying a lot about how stablecoins are revolutionary, how they can be profitable, and what they can do in traditional currency, finance, and trade, as if they want to implicitly express something.

But I just can't find that point they are subtly expressing.

Perhaps, they are just talking nonsense.
