Best thing about Paytm is that you can add money using credit cards and then transfer it to bank account, this way you save on cash withdrawal fees and any interest that you are liable to pay.
The app has a very easy to use interface and is also secured. This is the next big thing and is catching up as people know about it. Please try for yourself to believe.
