Well WHAFF is the well know for the online rewards paying.i have experienced the real fact about the app.i was using from past 6 months to gain rewards to redeem to playstore and other places. But I wasted my some time to collecting the rewards .because I faces many problems. That I cant able to redeem.in real.
There are many ways to claim rewards like installing apps and install for some days . And offers some points if your lucky. Now they offering bitcoins and ethurum . First you need a proper facebook like referring friends to friends my friends refer me but never got points.its just a worst time pass application. Dont try to install friends its just a dream
