I wish there was a miner that was 100gh or so...maybe 250gh? That was at least as efficient as the s5. I'd like something I could run an extension cord off the back of my computer from the power supply so I didn't have to run a separate power supply. Basically a lottery device, but a little beefier than these usb miners. I saw a miner that was overpriced called a technobit. I heard people just got scammed or I might have ordered one myself. The antiminer u3 sounded perfect, but it seems that it doesn't stay hashing without fiddling with it. The power would ideally be somewhere that could be powered by one rail on a PSU 60w-150w I think?
