Something I rarely see discussed is the risk around power regulation as it pertains to bitcoin. As virtual currencies become more popular and easier for people to utilize, the demand to create coins will increase. I've seen some articles discussing how mining coins has put a strain on some power grids that are already stressed beyond capacity. Could this reach a point where governments require something to the effect of additional carbon credits or such?
