Have you at all been interested in the rise of cryptocurrency? Do you think mining currencies such as dogecoin and its competitors can be profitable? I knew someone who had nearly 300 dollars worth of dogecoins mined using two computers in a university dorm. He didn't have to pay for electricity, so there were no problems there. How valuable could these currencies be to us as bargain shoppers? Do you think they'll replace traditional currency or is it a fad that'll wear off in a few years?
