I have generated a spreadsheet that should allow user input of all potential variables to consider when deciding whether to invest in mining hardware or in BTC directly.
Play with it, and tell me what you think. It seems that the wisest choice could be either, and it greatly depends on difficulty levels and expected increase (or decrease) in the price of BTC.
v1.1 - Difficulty should now accurately affect BTC production.
v1.2 - Added in calculations to show profits if production is traded daily.
v1.3 - Added invest/withdrawal/pool fees fields, added uptime percentage field.
v1.31 - Calculation/bug fixes
v1.32 - Calculation/bug fixes
Download the spreadsheet (v 1.32)If you find any errors in the calculations, PLEASE let me know so I can fix it!
