That pretty much sounds like church buddy. "you gotta have faith". I see a pyramid. Lowest plans go in debt. only if you invest more than the average will you earn anything. I'm not saying this isn't working for you, I believe your videos. But that can't work in the long term without exploiting low level and new investors. Your contract will cost you more than it earns because otherwise Genesis would just mine for themselves without you.
Beware! There be dragons here!
if you are right, then it's a good thing I earn 90% of my hashpower
Sure. But I think Genesis is promoting a scheme that only works for the high investors. Your videos make it look pretty good but it only works in your advantage if you're not actually paying for most of your hashpower. I would love it if you shared some videos on some good mining hardware and ways to save electricity while mining.
