I installed it for earning paytm cash.I started doing tasks given by it.I have installed many apps given in it.The problem is all about privacy, these apps robber our personal information and our device details.And next problem is they give only half the price they said.If they say we get 6rs for installing after completing task we get only 3rs.the next problem is we cannot redeem until we get 30 rs.after getting 30rs we can only redeem 10 or 5rs.ALL FAKE.
