Why all the countries hate cryptocurrencies ? Why they hate us making some money? They want us to be dependent on them for everything and if there is any opportunity for us to rise then they block its path. Same restrictive policies might be applied to our financial system, and that would be very damaging to all of us.
Most the Governments with few exceptions don't want us to invest and hold crypto currencies because due to decentralized nature of crypto they lose control on economy/money supply which challenges the credibility of Fiat based centrally controlled banking system. Money is a powerful tool which governments wants to keep in their control.
