Although stablecoin issuers have terrifying net profit margins and a very stable income source primarily based on government bonds, both the previous European 'Cryptocurrency Asset Market Regulation' and the current leading American 'GENIUS Act' prohibit stablecoin issuers from paying any form of interest to holders. It seems like the state is forcibly making issuers wealthy while preventing them from sharing profits with the public. In reality, this restriction leaves a last semblance of decency for the current traditional finance represented by banks, or it is also a final reserved space left by traditional finance in the game, firmly pinning stablecoins down to the realm of payment and settlement, castrating the savings and investment capabilities of stablecoins, and not allowing traditional finance to die too embarrassingly.
