My prediction: Chipping will start slowly by chipping bots that will sit 24/7 chipping it from multi-computer server (somones runing a 1000 virtual boxes isnt that useless now), once it gets closer it will become faster as more bots are put to work and humans start chipping too hoping for random luck. Noone will buy the pickaxe or if it will, it will be a publicity stunt (somone famous doing it for the luls). Evnetually one of the competing bots will win the game because humans are no match for it. The last chips will fly in nano-seconds.
Moral of the story: botting wins social experiments.
