Makes me wonder if it would be a good idea for game companies to provide a free copy of their game with mining software, maybe a week after retail release. Once the software has mined enough money it would disable itself, or keep going, but preferably not. People would get free games and companies would make money off of them.
It would be better than most DRM at least. According to the figures in the article it would take about 65 days of playing the game 4 hours a day to make 60$(you should check my math, I make no guarantees).
