Trading on intuition is expensive
Every Polymarket trader has been through this.
You can't test before you risk
You have a gut feeling about a market. The only way to validate it is to put in real money and wait. If you're wrong, you pay the learning fee.
You don't know why you lost
After a losing week, there's no way to replay what happened and understand if it was bad strategy, bad timing, or just bad luck.
Institutions have the edge
Professional traders backtest everything before deploying capital. Retail operates blind against people who've already tested their edge hundreds of times.
