Simple is that bitcoin is not authorized by government nor there is any news of banning it.bitcoin can be taken as virtual asset that now many indians are taking interest in investing their money in it so they can get profit.some of government members are against it because it is anonymous and before demonatisation black holders while hiding their money in it.
Don't take it the wrong way but how on earth a transparent blockchain like BTC can be used to hide black money? why do people still think bitcoin is anonymous?
transparent in which sense?have you ever read satoshi whitepaper ?,it clearly tell you that bitcoin is a anonymous asset.regarding black money,kindly check bitcoin price in during India demonetisation,do not tell me it was coincidence in sudden surge in bitcoin price.if you check bitcoin analysis report ,you will find there was a great amount of bitcoin transaction done during demonetisation period.
