hi, i have genesis mining contract too. I only use the basic 0.2Th for bitcoin and it does what it says it will do, but I have found that it is much better for me to mine LTC because of the payout limits. i get daily payments of large numbers of satoshi equal to what I would get if I selected bitcoin mining. The good thing about genesis mining on the bitcoin contract is that your one off payment is a lifetime contract. I paid using bitcoin which is why I get daily payouts.
