The population of the USA is approx 330mm or about 4% of the global population.
China on the other hand has 1.4 billion or about 18% of the global count

If 40% of Chinese were to invest in crypto that would be double the USA total population.
Staggering numbers.
Imagine what that would do to the whole crypto landscape.
And this comes from a country where Crypto is currently banned.
