China's GDP in 2024 was around $18.30 trillion, while US GDP was just over $29 trillion, while at the same time BTC market cap is around $1.88 trillion. If you understand basic math, then you should understand that no country will profit significantly even if they gain absolute dominance over BTC.
Here are some basic math: Bitcoin has an addressable market cap of more than $200 trillion. Currently, it is $1.88T, but I remind you that a couple of years ago, it was below $500 billion, and a couple of more years ago, it was below $500 million. Clearly, its growth resembles an exponential function, which will continue until it absorbs nearly everything that is treated as store of value, like metals, art and real estate; it's just not realized yet, because people are ignorant. Optimism isn't a bad thing, but I wouldn't really agree that it will be the way you imagine. It is true that Bitcoin has the potential to be much more valuable in the future than it is today, but I do not believe that it will absorb all other markets in the way you described. Art and real estate are very tangible and visible assets that people will always value no matter what they think about BTC. Even if you're right in some vision of the future, it would take decades to reach the $200 trillion market cap.

As Lucius said above, an asset with a market cap of less than $2 trillion, highly speculative, pump and dump at any time. How can it significantly boost or impact an economy with a GDP of $29 trillion? People are really hyped and overhyped about Trump and Bitcoin. Trump is just a politician and Bitcoin is just a highly speculative asset, they are not God or the panacea of this world.
Bitcoin was created as an alternative to the existing financial system as a cryptocurrency - and what is happening today has little to do with the vision Satoshi had. Unfortunately, somehow even politicians have found a way to use BTC for their political games, and it's even worse that everything is managed by a man who legally should be in prison if we were all equal before the law.
