I have profit 230%. It's very easy to setup everything, just deposit some BTC (min 0.1), find some good trader (I'm really recommend 3.14FX). You can specify amount which you can risk per 1 trade and maximum trades per day and thats all.
Personally I dont like trading with BTC (Im altcoin trader) and this looks perfect way for me to get some more money from my bitcoins.
