The technology is here to stay but not in its present form. The governments cannot allow anything unregulated. The idea behind the American revolution was to restrict government to what it can regulate. Freedom of speech, freedom of religion, freedom to protect oneself from aggressors, freedom to pursue personal happiness, etc. Lasted more or less for a couple hundred years.... May take another American revolution to put in place again because over the course of time these "freedoms" are eroding. There is no way they will allow freedom of currency exchange. They will figure out how to tax (get a piece of the action) and regulate.
