As of today , jun-18-2017 , With current difficulty / LTC - fiat exchange rate / 0.1$/kwh electricity rate the ROI is 1 month
i used 2 l3+ for calculation , as i have two from the first batch
i used 1400$/miner as a hardware cost , in this price included the shipping , custom fees
i already get back that money i invested into this miners
when you calculating your profit make sure u know how much u paying for electricity ($/kwh) included taxes , fees !!!
thx you ! would you call it worth it to have it in september with potential delay ?
considering what is been said above (gpu mining rig)...
thx
