Fortunately the device is not that expensive. 1 USB unit with 5 chips is $133 and the controller is $66 so the total cost of a 20 piece system is ~$2700 (¥ 16398). http://mall.diginforce.com/goods.php?id=39
2700$ for 20 devices for 6Mhs in LTC mode only, is about 30% cheaper than equal hashrate GPU mining rig
but the great saving is power.
.........
definitely we got 30% more profit whit 30% less investiment.
so i'm sad... i just ordered my 5 gpu...
- both miners and gamers are still in love with those nifty little chips from amd.But I think the price is about right for that scrypt-asic miner and if they are able to provide the scene with a steady supply we'll see an even more rapid increase in difficulty and thus rendering our nice little gpu-rigs utter useless for scrypt-mining soon. Sigh.
Unless you've got some crazy deal with free power and cheap gpu's (got free power myself tho. )
