While many stablecoin advocates have argued that U.S. dollar-backed stablecoins bolster the dollar’s strength by increasing demand for T-bills, the Treasury appears unconvinced. "
If I'm not mistaken, there are 193 countries in the world, almost all countries use stablecoins such as (USDT), (DAI), USDC (USDC), and others, only 11 countries have adopted a Central Bank currency (CBDC), Legally it is not easy to eliminate all existing stablecoins and make them one, namely (CBDC), it is not an easy matter and it is not easy to get support to make one and the others disappear.
I think stablecoins have now gained a lot of support as a single dollar, fiat currency combination asset in various countries, my understanding is that even though the US Treasury plans to make all stablecoins (CBDC), The idea came out while sitting in a rocking chair, but doing it was not as easy as they imagined. The US Treasury Department wants all crypto assets Bitcoin, Ethereum, BNB to be under their control, unfortunately it's all just a dream.
