Thats the point with any ASIC miner, if you live in a country with high electricity costs, its allways a problem, but look at these small usb miners with 2.5 watts, it will get you 3 ETH at the moment per Month if you mine ETH, so it is not a bad deal. If you mine ETH classic the difficulty level is way lower then from Ethereum, check this live link so see the actual Hashrate from each network.http://fork.ethstats.net/ the classic is aprox. 10 times lower then ETH, but the price is only aprox. 5times lower, so if you min classic you have way more money at the end, i didnt do the math exactly, but i would say with this little USB miner which cost 149 U$ you can mine aprox. 75$ a month with ETC at the moment. Any comments are welcome.
