Try my service. Is just a little risky (due to trading market) but you could invest just 1 BTC . I sent you a PM.
But how to be sure that this service really brings a good profit? Do you have such options where you can read the reviews?
I wouldn't invest in that guy if i look into his trust he has several unsatisfied customers. There is no such thing as garantueed profit, because if there was, he shouldn't need your money.
"Just a little risky", while at the same time you promise 100% profit? These two really don't fit together man.
Would like to see some more that will proof me wrong, but i'm very skeptical..
