i agree that regulation is not needed. i have a feeling regulation and intervention by authorities will do nothing to stop bitcoin as a whole. sites may come and go exchanges may be brought down by their own incompetence or by local government intervention but another will pop up and take its place thats what so great about bitcoin anybody can get into it not just the people who currently control all the wealth . exchanges will just move to places where authorities have no jurisdiction.  I am for some regulation when it comes to user safety and fraud protection but cant stand the regulations that keep corrupt people and businesses in power.
