Sorry to crush your dreams, but this is most likely a Ponzi scheme. The fact that you were actually paid has nothing to do with this. This is how Ponzi schemes work. You were paid from the money other people invested and they will get paid from other peoples' investments. That's why they need to be constantly bringing in new investors. Yes, you might make some money, but get too greedy and you'll loose big time.
Also, I've had a look at their FAQ section and seeing how they GUARANTEE you that you'll keep your hashpower for lifetime (meaning they GUARANTEE you a constant payout) this is almost 100% a Ponzi scheme.
And my last point; 100 KH/s is a comically low value for Bitcoin mining. If you did your research (i.e. do a quick Google search) you would see that with 100 KH/s, even with NO electricity costs, you would be making around $0.00000295 per MONTH! And they're promising you $1.20 per day?! There is no way these guys are legit.
I hope you see this before you loose your money! Seriously, what's too good to be true, probably is.
You are 100% correct. Hence why I only put in $11.99, and won't put another $11.99 in until I've made at least $48 in profit, so that I've doubled my money. Then I'll wait til I've made $96 to invest another $24, etc (for a total of $48 invested). See where I am going with this?
I see where you're going with it, but I still have two complaints about it.
Seriously, don't play with fire. You'll get burnt sooner or later.
