Believe me paytm is just for saving in all fields whether it is shopping ur recharges , bill payments and many more. I have earned almost rs 2000 also with paytm ? How . for every number registered in paytm it offers rs 15 for every new customer joined. I took all the numbers of my relatives and registered their numbers on paytm and by registering them first time on paytm and entering a coupon FREE15 every one got rs 15 and I transferred this to my account. Normally I submit the electricity bills of my whole colony and for every bill payment I got rs 50 cash back on my wallet. So you can also earn via same. Ol d best
