Unfortunately the government in any country has the ability to take away cryptocurrency or even regulate it. One of the main reasons why the government decides to ban cryptocurrency is because they are not able to regulate it enoug.
They will not stop making pressure to cryptocurrency especially when this market grow more in the coming years, so for now let's keep on believing that our government will support this technology.
Just relax. From that situation I think that they are carefully studying about crypto and blockchain whether it will be a threat to their economy or not.
Hope that every government have their own legal team to study well the cryptocurrency and comes out to a good feedback.
No team is able to convince the government that bitcoin is good. It should be understood that in all countries the government consists of rich people and acts in the interests of rich people. No one voluntarily you the freedom are not present. You have to fight for it. It seems to me that the crypto-currency community is very divided in order to resist the world clans.
