Here's the beta version of my Cryptocurrency Mining Farm Excel Sheet. It allows detailed recording of the price and build of your rigs, hashing power for up to 12 cards per rig (dual currencies are supported for those of you dual mining), and financial stats such as historical profit from selling off coins, amount and value of currently held coins, and a pricing calculator. It uses the Cryptofianance add on so you may need to download that from the google sheets add ons store. If you like it, feel free to go to File > Make a copy, and tweak it for you own use! If you have any questions, suggestions, or bugs, please leave them in the comments and I'll update and hopefully perfect the sheet over the next few weeks. Enjoy!
Current numbers are just place holders and don't necessarily reflect the actual price of a rig.
