Governments, worldwide, have clear goals: to become more powerful, omniscient and perpetual in power, and the basis for this is the money they hold. Crypto currencies attack precisely the money part and consequently affect the other objectives.
The currency digitization movement is global (e-dollar being proposed by the FED, e-Real in Brazil, the digitization of money in India, as well as the banning of cryptocurrencies mining in several countries, claiming: * put your ecological/anti-terrorist argument here *.
The truth is that governments do not tolerate the loss of control and the possibility of currency evasion that cryptocurrencies potentially allow. They also don't tolerate the possibility that when they do shit, they can't print money at will to try to cover it up. Neither do they tolerate not having control over all circulating money, especially with regard to taxation.
Laws like this will continue to be passed easily, worldwide, as it maintains the status quo that governments will do everything to maintain.
PS: I am PRAYING to be wrong on ALL of the above statements....
