That's easy.. Deadcoin^TM. It will probably launch sooner or later this year.. only mineable by PoD (Proof of Death). If you have a valid death certificate and can prove you are closest of kin you can claim someone's Deadcoin.  Total circulation will be equal to the total world population (roughly 7 billion on march 12, 2012) at time of ninja launch. NO pre-mining by world dictators through war and mass starvation will be allowed!!
