yes I think for overall decentralization it is not but if data decentralization is true
USDT is not really backed up with real USD, I think it is like that, even in the real world USD is in fact not backed up with gold and can be printed arbitrarily without requiring permission from the IMF
This is indeed a big fact, where many use cryptocurrency easily and are recognized by cryptocurrency enthusiasts
We already heard a lot of rumors about the fact that USDT is not supported by real dollars, but all these rumors have not been proven. I believe that this stable coin is the only one on the market that you can hold in your portfolio.
