This program calculates the amount of Bitcoins you should accumulate by or earn on any given day at your current speed and the current/future difficulty.
The difficulty estimate uses a proper amount of days for the difficulty readjustment (2X difficulty = 7 days, 1.15X difficulty = 12.174 days)
Please post any suggestions or comments you have.
Instructions:
