Governments of many countries are practically declaring war on cryptocurrencies.
Why is that?
Governments dont understand Bitcoin and want to control it. It is true that Bitcoin and other cryptocurrencies will be disruptive to banking as we know it. This makes them want to hold Bitcoin back. Governments also want to make sure they get their taxes from us as well.
Absolutely true mate. Government will not banned or make bitcoin illegal as long as they can collect taxes from it. Mostly the reason behind the illegality of bitcoin declared by the government is because they are having a hard time to trace every bitcoin transactions and to how they can collect taxes from the holders not unless the holders itself converted their bitcoins into fiat. But as long as it remains cryptocurrency in the wallet it is decentralised and controlled by the owners itself only.
