Hello. It's great for you to have such an enthusiasm ! IMO though you are paying more for electricity than that you are earning by CPU mining DOGE. I recently read an article for CPU mining where they described the whole thing as if it is absolutely free because you can mine while the computer is not in use. But modern CPUs consumes many times less electricity when the computer is idle, so when you start mining the power consumption really jumps up. You can try those USB ASICS and I think that you will earn more money with such a device(s) mining bitcoins.
Yeah I understand that however the idea is that if you can accumulate a good amount of coin while the value is low and it continues to increase in value it will pay off in the long run. I have heard enough hype about Doge in many media avenues to take the risk to spend some electricity to get some coins and see.
Of course it could all go bust too you never know.
