I believe anyone has to right to use bitcoin. the value china would bring forth of course is clear; I mean they are one of the largest countries and you are basically enabling more demand on bitcoin. which means higher value.
obviously I want china will come back in bitcoin world. china has a great contribution in bitcoin field. when china banned bitcoin a huge change occurred in currency.
Yes i also want China back in the market bitcoin China has a very big population and it can really give a very good support to bitcoin, to me i think that in future when they will realize the need of bitcoin, they will surely start accepting bitcoin as legal currency, because bitcoin is the need of the day and bitcoin is going to become the main currency of the world.
