A note on risk —

A clear regulator does not make a platform safe to over-trade. Prediction markets can lose you money; trade only what you can afford to lose, never to chase losses, and never on borrowed money. If it stops feeling like a choice, step back. In the US call or text 1-800-GAMBLER or visit ncpgambling.org.
