In case you are interested I have published my payouts over the last month, and did some calculations on it.
You can find the article on my blog: Payout on Genesis mining.

I have already got my investment back and are expecting a nice profit towards the future.
If you have any questions let me know, but I think the number speaks for themselves.

edit: this article is about BTC. I'll try to run the numbers as well with other coins like ETH.
