What we all dread is the total ban in the use of cryptocurrency because that mindset can be a loss-loss situation for the Bitcoin holders and the government. Even if the government will really not encourage anyone to go with cryptocurrency, sometimes the most important thing is that nobody is barred from joining the Bitcoin ship.
I don't think they will ever ban it now it's grown so big. If they were going to ban it the US would have taken the lead and done it when the Silk Road was closed. It debated it, then decided not to because Bitcoin had too many positive aspects.
The fact Italy is trying to regulate its exchanges shows it has no intention of banning Bitcoin.
