Actually I don't see shitcoining as an attack to Bitcoin more than gambling is an attack to the USD. It's rather an attack on people, temporarely diverting them from understanding true, sound, honest money. But this is more like a tuition fee at the University of Life, they will learn their lesson the hard way and probably will becoming more bitcoiners than others that were just lucky to have friends who guided them by hand directly to Bitcoin.

My take on the game theory is that rules are self enforcing and people being greedy and following self-interest are benefitting everyone, like for example miners. Bitcoin and the whole human race live in a super- symbiotic relationship, as individuals we can act according to our own will and altogether benefit the super-symbiont which is our society
