Once I though I would promote to Master. Then I spent half my net worth on what I thought was a safe bet related to the Mario movie. If I try hard, will I be able to avoid demotion to the Platinum League?

This market resolves YES if I stay in the diamond league or promote to Master, NO if I demote to the Platinum League, N/A if I stop using manifold regularly (defined as a week passing where I do <5 bets)
