I think stablecoins are how we win.
USA is in an existential battle to keep USD global reserve status - it is the basis of their economy, they're fucked if they lose it and trump clearly knows.
The war is for users - that's what makes you the reserve. Used to be you could get users through their governments via bribes and threats (as well as genuine utility) but in the future plebs around the world will want to use what is on their phone etc - and governments have far less control.
USDT are literally USD. Trump will want as many people as possible worldwide to use it and any other USD stablecoins. They won't want any barriers, or kyc. They might even get eg NSA involved to help make sure governments like China cannot stop their plebs using them.
In this arms race cbdcs will be DoA as they depend on coercion. Only currencies that are freely useable, which you can go into and out of with minimum friction, will have a chance.
Everyone will be able to have wallets with these things, plus shitcoins, and bitcoin. But once you have free competition like this,, the best currency wins.
