China has completely banned cryptocurrencies in order to prevent capital outflows!
Chinese officials are unable to effectively regulate cryptocurrencies, so it is forbidden that these bans are partly to prevent money from pouring into some fraudulent ico projects.
But we can see the people from that country are using crypto currencies on a large scale which shows that none of the government can ban Bitcoin and other crypto currencies. Actually the people from China know that Bitcoin is a decentralized currency and no one can own it but only these people are the owners of their own coins. If we all keep that concept in mind that no one will harm Bitcoin and it will flourish all over the world.
