Something happened a few days ago. My friend joined a group where sports betting code is sent now and then, but whenever he chooses to bet, the game dont go in profit, while whenever he decides to pause, people win in the group. He then decided to be consistent. While being consistent, he had a series of losses from that same group, until he decided to stop gambling completely, only to see the recent code keep turning out to be a win.

Should he stay consistent or quit after so much frustration?
