I'm looking to do some hardware purchases, but need the hard numbers to plan out the mining biz...
Does anyone have an accurate formula or spreadsheet to start with? I imagine the variables to be:
- Current difficulty
- Projected difficulty increase and dates
- Rig speed
- Hardware upfront cost
- Hardware maintenance cost
- Bitcoin price
- Power consumption
- Price of power
Am I missing any variables?
Primary question right now is how to calculate possible coins recovered based on current difficulty and Rig speed?
Any advice here would be most appreciated.
