Updated: 2026-07-05 · Author: HiYesNo Content Team · Type: Academy article

Prediction market prices can help users understand participant probability views, but probability is not a guarantee. Position size determines how price movement, liquidity, and resolution affect an account.

Before participating on HiYesNo, beginners should define an affordable amount and avoid oversized positions just because a price looks likely.

Key Points

• Understand the concept before reading price.
• Price and probability are not profit guarantees.
• Managing size and risk matters more than chasing certainty.
