Not all governments hates bitcoin, Japan is one example, they legalized bitcoin instead of banning it. Other countries are not yet prepared to allow bitcoin to become of their optional currencies because of its decentralized nature. They might need more time to study it first like what will be the impact on their economies if they freely allow their people to use bitcoin and other cryptocurrencies in their transactions.
Japan is an exception. There can be many more countries to follow. But none will unless their faith is put back in place. This could even be trust. A trust in the system. A sense of trust that no one will manipulate the system for their own personal gains.
