Thank you for that insightful post. I'm also mining at genesis, but I see steadily decreasing my payouts (due to rising difficulty). I've calculated that I won't reach break-even (in terms of invested BTC) if payouts continue to decrease like this.

What have been your experiences so far? Did you net the amount of BTC that you have invested? I feel like you have to upgrade constantly (and rely on promo-codes), otherwise you won't be able to gain profit.

Is it just me or did you make a similar experience?

Have a nice day!
