Is The $750 Cash App Real? No, it is not. However, there is no Cash App official stamen made on such kind of feature as of now. So, if you encounter such offerings during the course of using the Cash App services, you don’t need to get involved. If you do, you will not only lose your money from your Cash App account but you can also lose your Cash App login credentials. Take a look at the official Cash App section if you need it!
