Hmm, first you come on here (as a newbie) telling us you doubt the farm even exists, now you are telling us there is no chance of ever catching difficulty.
Does it pay well in Club Troll?
Maybe the newbie can do basic math? Difficulty is growing at >1% per day (short term even 3%).
1%^7 = 7.2% per week.
1%^30 = ~35% per month
Your shares represent 15 GH/s each. To just keep up with difficulty, that would need to increase by >35% per month or ~5GH over the next month.
Lets use tsm13's optimistic estimate for mining revenue: 0.002393 BTC/share/week and lets even assume difficulty wouldnt go up this month. 50% reinvestment yields ~0.0005 BTC or a bit over $3.
$3/5GH =$0.6/GH. Good luck with that.
