It will never happen. They can't win over bitcoins. Its not in under control. You know the bill gates statement ? Bill said " Bitcoin is unstoppable " which cleared that there's no power who can wins over it. Main problem is banning bitcoin sites like wallets and so ICO which gives ability to invest our coin and increase there value by selling coins later at exchanges .Chinese government tried their best to stop bitcoin but fail at the end, but they still manage to ban the use of ICO.
Yep, absolutely it never occurs. It is really clear that bitcoin is developed as if the advanced techonology. Most importantly, these days, people almost can not live without internet, thus it leads bitcoin to be more developed, even its demand will be high in most parts of the world. Honestly, the development speed of bitcoin is really quick, that is one of the reasons why most of governments try to prevent people from using it. In anyway, they will never stop the development of bitcoin.
