I wonder how we're able to pay our clients every week 
You asked the question that everyone including myself wants to know the answer.
you must show evidence of where the money comes from to pay the investors, if you can show these proofs then you will win many clients, of course it will depend on the evidence that you will show.
So, are you going to show the evidence or not?
We're still waiting for 100% proof that we don't truly payout to our clients and I would be glad to see someone try.
this is what all scammers running hyip/ponzi sites say, just show us evidence of where the money comes from to pay the investors
