Only risk what you can afford to lose
A price is a probability, not a promise. Any single position can go to zero.
Set limits before you start
Decide a maximum amount per week and per position, and stick to it. Position-sizing methods such as Kelly are guides, not guarantees; many traders use a fraction of the suggested size.
Warning signs
Chasing losses, trading money meant for bills, or hiding trading from people close to you are signs to stop and seek help from a local support service.
Age and local rules
You must be an adult and follow the laws of the country you live in.
Practical limits before you trade
Decide in advance how much you are willing to lose in total and never add money you need for rent, bills or savings. Treat that budget as spent the moment you deposit it. Set a time limit as well as a money limit, and take breaks after a loss instead of trying to win it back quickly.
Prediction markets can feel like investing, but outcomes are uncertain and prices can move fast. Keep a simple record of every position and the reason you took it — reviewing it later is one of the best ways to spot emotional decisions.
Warning signs
Chasing losses, hiding activity from people close to you, borrowing to trade or feeling anxious when you are not checking markets are signs to stop and seek support. Many countries have free, confidential gambling-support services; your local health service can point you to one.
