Where do you get this idea from? Sounds overly optimistic and ignores a ton of problems the USA has with crypto right now. SEC has been suing people left and right, while their next target is clearly stablecoins in the near future. Even if those coins did survive, why would you think people need to move to the USA just to use them? I'm not going to lie, it sounds like you're just pulling things from the air and doing US propaganda.
Look the future stablecoins USA have usdc, usdt,dai,busd..guess what binance.us still operating in USA it's evidence of further busd plans.
But off course first there would be crash and then you have crypto you USA for cheap.
Europe not bad either tether stable coin for europe.
USA is when private companies like circle blackrock and coinbase will provide new financial service.
It's not bad thing that USA will be like dubai kind of country and crypto and Stablecoins innovation hub.
And there Will be no cbec like any other countries USA Will use existing blockchain btc eth trx sol xlm the legit ones to give power to privacy and private ownership of capital.
And we can expecting trump to come power next year trump support always free markets and that's what usa is all about.
Just the future of each country new currencies...youll see usa will use most freedom supported currencies like USDC and usdt
