So I told a few people I'd do a comparison of a few mining services. I purchased 5 MH from Genesis Mining and 5 MH from the new GH Ethereum Contracts. I bought them on 5/18/16 so this week is a partial of course.
This is also not going to be an extremely in-depth thing. I'm going to basically show the numbers. If you really want all the data, hit me up and I can provide it.
Purchase Cost: (purchased with BTC, but I converted to ETH at the .028 BTC/ETH rate for easier comparison).
GM: 0.13687966 ETH
GH: 0.114429702808988764 ETH
GM: 0.939 %
GH: 0.967 %
