Hahahahahaha! Now that is funny and if this is for real, now I see how the whole idea of smart contracts and blockchain technology as a whole has been turned to joke.
Empower people with grudge around the world by bringing blockchain transactions into a private killing contract? How bigger can the joke get? In fact, this is like the highest joke of 2018!
RE: KillCoin: Have a grudge with anybody? This is the coin for you!
