This tool auto pulls in the current bitcoin price and allows you to see how much you will be making by a given day. It also automatically calculates and subtracts Hashflare's maintenance fee.
With the volatility of bitcoin prices and the inconsistency of the difficulty to mine them, we realize that this app cannot be 100% accurate. However, we do believe that it will give a good projection of your potential earnings.
