with this prize fall its impossible to ROI and difficult increase doesnt help....
If this continues and BTC doesnt go up i will sell all my equipment

Thank God people think like that! Please sell your equipment! If you can only think in BTC terms then you are better shut down your machines!
I made 0.025BTC/day with 500Ghs this month! Thats 0,75BTC/month! If you know how and what to mine then the possibilities are infinite!
Hi would explain How and what to mine? you says 0.75 BTC/month , thats ROI on S3 less than month
