Are buying 3x USB Bitcoin Block Erupter ASIC Miner 330MH/s worth it?
I seen these on ebay and I was just wondering if they would be worth it to mine and I was just wondering if I were to mine at least 10hours a day for a month, how much btc do you think I'll make? Just a brief estimate would be nice or just a realistic opinion about buying 3 for $15 each
