I think its comical some people in this thread think china is "transparent" in any capacity. Their very cultural dictates this isnt the case. They are THE most manipulated currency to ever exist.
The whole world will be cashless soon and here is how:
The world debt is out of control. SO you have to blow it up in order to A, not have to pay anything back and B, give a reason as to why extreme measures will be used so "it never happens again".
Once it has blown up, everyone will be tracked and you will need "something" to buy and sell, could be a braclet (which is already being used in Israel for covid so it transfers easily), or maybe the chip that Elon is making that can be installed in your head (he wants it to be ubiquitous, as easy and cheap as getting laser eye surgery) can house other data on it at some point. Either way, that gives rise to the blockchain network which is how everything will be tracked monetarily.
