Recently I found this Site as an opportunity to exchange some money from my SolidTrustPay account, which I couldnt withdrawl to my bank account.
So I registered at www.wcarev.com and invested my dead money without too much hope.
It's pretty amazing. Your invested money will be given back to you after some weeks. In the meanwhile, you're advertising your PTC sites.
My starting money has grown to over 100$ now - so I will get my next 25$ in fewer time!
So, why dont you give a try? The minimum invest is 2 Dollars. You may pay with Payza, STP and EGOPay.
I hope this Site will last forever!
