Or no fork.  There is no cryptocurrency variant that is immune to regulation where it transacts with the traditional financial system.  Forking bitcoin or creating new alt-coins simply will not solve the problem, to the extent that is a problem, of regulation at points of contact with the traditional system.  We can already go both routes.  If you choose to only transact in bitcoin, then you can effectively choose to transact within an unregulated system.  If you want to move into and out of bitcoin and the methods you choose to do so interact directly enough with the traditional financial system, then you'll likely brush up about regulations.
