90% of that 9$ goes to electricity fee, why adding that with your real profit? That's not how mining reward is calculated, separate electricity fee from the reward, the rest is yours... 380 GPU is old, not profitable anymore but if you have free electricity then it's good
i realy have 95% free electrcity
With 47MHS mining ethereum with AMD 380 you really can't earn more than 9$ or 10$ if you have free electricity, you can't try downloading Nicehash miner, this miner will adjust your Hashrate to the highest as possible
