Nah, they won't ban it, it's just another area they can tax and add to gdp when they need to
But why they need to collect tax from bitcoin? What they are going to do with that coin? And i think they can't added to their gdp because they not own it and its decentralized. They don't need it, they just want it. They want everything.
Yes the ridiculous government is waiting bitcoin to grow more as they can find the source of income out of it too in the form of the taxes they would never banned bitcoin as they are aware it is the future of the currency and they are aware that it is gonna profitable for them in the future.
some of those governments fear it because of this actually, because they will know that if they want to evade taxes they can do it with bitcon, and everything at their disposal
this is why some nations are banning it and some not
