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..
Risk depend by how ppl want to earn. If you would double fast your investment and left me trade with leverage 500, loss risk is high. If you like to earn about 30-40% weekly, you left me trade with leverage 100x or less, and risk will be really low.
