already china has banned bitcoins is there any chance that other countries may ban bitcoins?

China did baned bitcoins , but the miners and the users can use bitcoins .the ban is for converting BTC into cash by placing them in banks .
And about the ban in other countries , it could be because of the anonymous nature of bitcoins transaction. People can fund illegal activities using BItcoins without disclosing their identity.
The other reason could be that bitcoins need people to be educated enough to use and operate a wallet .
