> GPay gained success by offering scratch cards (giving you money) and cashbacks for making payments through GPay.
I remember reading about some anecdote where a network of friends were doing thousands of transactions a day to game the scratch card system. I'm sure they plugged that loophole (if there was ever one) pretty quickly.
Scratch cards "drawing dates" several days after the transaction. Enough time to figure out ring transactions. Google once targeted a friend by making his meal nearly free. He talked about that to several friends for months. His circle got much smaller rewards. Its not truly random.
