Yes Marcin. You are right " Halving took place 9th of July 2016". But remember after my last buy of hashpower the bitcoin raise 10 times. I bought hashpower, how can you explain that my hashpower was reduced to 0.
In comparison at the same time I bought exatly the same on hashflare and after two years they keep paying. I could not be an expert in some issues, but I don't like sand in my eyes.
And you are saying that genesis mining is not made for small investors.
