Every other Alt-Coin would be long dead by now if it had to take the beating that FeatherCoin had to take.
Yeah it's a good thing someone cloned litecoin and renamed it feathercoin to give these people something to attack because you're right, a 500 megahash attack on LTC would have rendered it long dead (although had they attacked LTC instead it would have been referred to as a "3% attack" :lol:)
