i dont think china control it . but chinese maybe . they are good at this type of work
What? Do you think that it isn't China but the Chinese maybe? People living on China are called chinese man. They know a lot of things when it comes to money making and they are the masters of reverse engineering. And I'm pretty sure tjey are one of the biggest contributor to bitcoin but doesn't have total control.
there is no doubt about this that the number of bitcoin users are more than any other country, their contribution is much more that any other country, but still they are not controlling bitcoin, as bitcoin is not under control of any country because it is a universal currency decentralize currency and not belong to China only
