Basic profitability math in a cloud mining crypto currency domain

Hey everyone,

I was looking into buying some cloud hardware for mining today. Found a cloud service genesis mining and did some basic math to justify an investment for me. Got disastrous numbers. Is it my math is wrong or service is a scam? Here are details — http://leonov.co/2017/сloud-mining-profitability/

Thanks in advance for the provided feedback.
