It seems to me that China has banned bitcoin for the purpose of publishing its own cryptocurrency, but I do not believe it. China has not yet reached such a powerful technology. I am more concerned that they are afraid that bitcoin trading will cause disorder in the economic market.
afraid? are you joking?
china GDP = 11 trillions USD per year
do you know what it means that? you need over 60 years to count this amount.
BTC means nothing for China. They can spit on BTC and it's gone; same as USA.
