We just finished another contract for 20BTC investment

That means?....
When someone contact us before big investment {more than 1btc} we send a contract so the things is not so simple for us. We provide all the info about the program and if you sign the contract you agree to give us the coins and we agree to provide the minimum of 7.5 or 15% monthly 3 times in month, if we earn more you earn more too.
Ok but how can we trust you?
You can't, thats why I'm not hiding behind profile, and that's why we are in gambling section, to know who you giving your money. If it's going like that next month we can stop new investors. Our target is to work with around 200-300Btc, if we use more we will overcome the market and there will be only trading between our bots. Wehave that problem, yes. If we hadn't have that our interest would be like 3%.
