Need to send $1 to you to start earning money. It makes no sense. Why would you pay money for me without any effort from my side? The only kind of site who really pays us for nothing is the faucet, even we need to complete a little task (captcha) to receive the reward.
But looks on your side we don't do nothing and still earn money... Ponzi schemes work this way. And if it's not, how is the profit make to pay all users and "investors"?
You still have to find referrals, they need to deposit and than you can earn. Its pyramid. You pay 0.01btc to activate account, than you find referral, when he pay 0.01btc(7$) fee you get 2.5$, and when he finds referral and his referral pay fee 0.01btc he get 2.5$, i think you should get some commission from his referral too. At least pyramids work that way. Its not really helping people, its more like helping OP to make money.
