Most likely nothing will help here. The very essence of the crypto currency does not like the government. Well, only if the Crypto-currency is not decentralized, then it will not prevent the state. However, then the whole meaning of the crypto currency is lost ... it will be just a digital currency ... which has very little impact on the world.
I think Maybe then the Government accepted their request and legalized it.
There is also a possibility that the Government is issuing their own crypto digital currencies with certain rules and controls from the Government, so the possibility of legalizing Bitcoin will be very low.
Everyone cannot force the Government to legalize bitcoin. With the passage of time, when more and more people will come to flip bitcoin and will start using bitcoin for their payments; then the majority of people will increase the demand to make bitcoin legal currency.
