"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.)
Crypto currency is nothing more than a new scam and an attempt at a new road into a CASHLESS SOCIETY! Considering governments are capable of shutting down the internet at their whim, how well do you think this beloved innerweb money is going to fair when complete access to it is cut off? Why is this simple fact so hard for people to understand?
Plus blockchain is 100% traceable.
Not all. And only to a wallet address. You cant tell us who has how many bitcoin today.
