Hi,website was down because we was improving the system for 2-3 hours.It is back online again.About the calculation of profit:If you make a investment as 0.1BTC 0.12BTC will be your total return amount.So your profit will be 0.02BTC.And yes we will give all the profit to the investors because there is a lot of sites out there and we should serve a good profit.But after the first month we will give the profits to the investors and keep the money for the bankroll.Please keep asking if you need to know more,thanks.
