Off with your head!* Bitcoin revolutionizes illegal actions -- does it hold your interest?

Any tool can be used for good or for bad. Bitcoin's revolution for good is insuperable from its revolution for bad. The good outweighs the bad, so it is a net benefit to society.

If you cannot see any reason for anonymity other than illegal activities, then you have a very narrow scope of imagination.
