Digital currency is to change the world, many of which were positive, to a certain extent, they pose a containment of the government, gave the people an alternative, but that doesn't mean they don't need to be regulated.
One of the core reason is: anonymous, do not track, not regulated digital currency will make form a closed loop technology crime, money laundering and terrorist, and disappear from unsolved bits, bytes, while the impact damage with each person in this world.
If every penny of extortion is tracked, is there enough motivation and courage to launch a WannaCry to attack the world?
There have been many improvements and developments in the field of digital currencies in the past few years. But still a major proportion of the world is not using them. I think that in order to fully utilize the potential of the digital currencies, they need to be regulated. Proper regulations will remove the fear of large amount of population and would also endure that criminal acts are not taking place.
