When you look at bitcoin, China is already the super power.
Most mining farms are based there and a lot of exchanges as well.
The economy in China is already amongst the top five when you look at the national output. And it has the strongest growth rates.
In a few dacade its military capabilities will at leat be equal to those of the US.
China will play its role as a super power in the future, there is no way that will not happen.
It terms of bitcoin, they are already a superpower, they have the most numbers of mining farms in the world. And it the trading, I think they are also on top per 24 hours trading, together with Japan. They also have established exchanges, although it was later found earlier this year that they are doing fake volumes by the PBoC.
As far the global economy is concern, they are behind US and may even overtake them in few years. China has really made a big transformation in the last decade or so making them the superpower that they are right now and still moving forward.
