Go cheap get some ltc3 asic miners down clock them to use 500 watts. 4 pieces is all you need. you will do around 1.5 gh that is about $1.50 usd a day you would also earn around .25 usd a day in doge coin.
1.75 a day = 52.50 a month.
4 l3+ miners are about 200 usd with apw3 psu's if you lived in usa shipping would be cheap being in Brazil makes shipping hard and costly from a USA seller.
it is about 280 to ship that.
doesn't make much sense, remember I got a rig already, the DAG is the problem... my rig makes about that what this ASIC would do
