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.
