Trying to figure out which ancient GPUs you must be mining with not to make a profit with 0.06 kWh power.
Are you using the old Radeon 6990 to mine?
Hah you're pretty close. I have zero initial investment because precisely that fact, its made with my old gaming cards. HD 6950 1GB and R9 270X 2GB. The R9 270X alone is also not profitable.
I have a couple of old 6990 rigs that are even worse power hogs and they still make a bit on cryptonight. Cryptunit has a nice thread and sute on the more obscure cryptonight coins. His realtime profitability data is excellent compared with whattomine.
