"One day everyone will use China's digital currency"
You think patriots would let that happen?
(Note that BtC has popped almost x6 since about the exact date this article was published last September. True, the fiat dollar bloated, but by nowhere near enough to justify even half of that move.)
I can see it with my own eyes with the artificial pump on Bitcoin. Anyone can see that a lot of money got moved over.
For all you know, 95% of the volume is wash-trades painting the tape to fleece the FOMOs and then rape their stops.
How could you tell otherwise?
