Yeah, it's going to be insane honestly. I can bet you a million to one too that many of them will be KYC'd or tied to your real world ID in some kind of way. I mean USDC pretty much already is if you go in and out of centralized exchanges. And they can track the hell out of and those wallets too. I recently had an issue with Robinhood closing both mine and my Mom's crypto wallets because I moved funds from her wallet to mine and then later on moved a different amount from that same wallet to my Robinhood account and boom flagged and shut down. Basically USDC is the CBDC already.
This is why I am ditching them all for Monero, lol
Regulation is going to require KYC, you can bet the ranch on that one.
Hence why I have pretty much stopped using stablecoins for anything other than trading on DEXs. And even then I have really changed my OPSEC so that nothing is tied to any wallets of mine that have touched a centralized exchange.
Other than that... Give me $XMR and $LTC with MWEB! And I am mining those too!
