Responsible Risk Management

Engaging in prediction markets and trading event contracts involves financial risk. It is crucial to practice Responsible Risk Management at all times. Never invest more capital than you are prepared to lose, and understand that past performance or current implied probabilities do not guarantee future results. If you feel that your trading habits are becoming problematic, please seek professional support or utilize limit setting tools available on the exchange to manage your activity responsibly.
