What you dream about has the same chance of happening as if you wake up tomorrow, open your BTC wallet and see that Satoshi sent you 1 million BTC

China as a communist country will never accept anything that it cannot control and that is why they banned BTC - and India is not far from doing the same in the future considering some of their crazy ideas that they already had and the fact that they are increasingly moving away from the West and they connect with China, Russia and similar countries, especially when it comes to BRICS.

Even if this were to happen in some strange development of events, one should not live in the belief that Bitcoin as a legal tender means that people will use it - the example of El Salvador has shown this best.
