High volatility is not the main reason why governments make bans, as I said before, they just don't want Bitcoin to be popular and always used in those countries, actually it doesn't matter to them if Bitcoin can be controlled, the problem is that Bitcoin cannot be controlled. So we can assume that the main reason governments ban Bitcoin is because Bitcoin cannot be controlled or is decentralized.
The future of Bitcoin is in safe hands, there are more promising sectors in the space and its all just a matter of time before bitcoin will hits the top priority for which it was invented into the space. This is crypto space, the ways things are done here are quite different from the real world, we just have to be acquainted with the system as long as we're interested in making new heights. The government is frightened by the heavy domination of Bitcoin in the space? I do concord with your opinion, because the market is filled with volatility, at the same time it have explored more given chances of investors and traders to make huge profits in the market.
