Hey guys I made a very extensive cloudmining comparison sheet which allows you to make an estimation of future mining profits using difficulty and mining growth rates. However I am missing one important function to automate the whole calculation.

Explanation of the sheet and the missing function can be found in my latest post: http://bit.ly/2KUlVp2

I have a bounty of 25 USD in crypto of choice for the person who can tell me the function I need (+ a mention in the sheet :))! I really hope someone can help me! Thanks!
