When last did you heard of CBDC, last I saw a headline about it was Trump was getting it scrap and banned, I haven't heard anything about them again. It was a party agenda to create a competition with Bitcoin as a blockchain for transparent money payment but it failed and it didn't just failed, it was a beautiful one for that matter and Bitcoin that has been mocked years back is doing wonderfully than ever, this is to tell you that propaganda doesn't last in tech.

Take a look at Bitcoin mempool, a single input output would cost you less than a dollar, where is it done in the US payment system? You will pay fees that are ridiculous. In some other countries you are going to pay vat from the sender, this isn't applicable to who received the money instantly. This is what Bitcoin has done that no technology hasn't been able to beat all this while, the technology and the concept has never existed before now, even the ones trying so hard to be like Bitcoin aren't close.
