I guess that is good news, the cat is out of the bag and no more rumors. China closes all exchanges based on the fact that they are operating without a formal license.
Which means there will be regulation and licenses coming soon, a good step forward.
Yes, we shouldnt bother this news that much. China may have a large population, but not all people are using bitcoin, only some. So, it may afdect the economy of butcoin, but not that much.
