that's right they are panning to put taxes with exchange so they can benefits with btc, might be much better instead of banning bitcoin we should be happy if government will place some actions to make some earnings too like taxing local exchange in our respective countries in this way adoption or recognizing bitcoin will be much possible in every nations.
That depends on the government. If they think that the benefits (tax revenue, reduction of crime.etc) will be more than the drawbacks (tax evasion, dark markets.etc), then they will legalize and regulate the Bitcoins.
Yeah i think there are already some countries in asia that's looking into and making studies on how to make bitcoin beneficial both to the government and its citizens. I've read that in the philippines, the central bank there is already finding ways to legalize bitcoin. I think we're niw in an age when digital currency would be introduced and more country would implement its use, nit just bitcoin but digital currency in general. We may have more people engaging in trading alt coins as well as investing bitcoin for long term. Btc may be illegal in some countries but as more and more people are using it, these countries may have to give in and legalize bitcoin
