BigONE Prediction Market User Guide

1. What is a Prediction Market?

• You buy shares of a certain outcome (such as "Home Team Win," "Draw," or "Away Team Win") to express your expectation of the result.
• Each share will ultimately settle at 1 USDT (if correct) or 0 (if incorrect).
• The price represents the market-implied probability.
• Example: If the current price of a result is 0.53 (53¢), it means the market believes there is approximately a 53% chance of that outcome occurring.

2. How to Participate?

• Place orders using USDT deducted from your spot account.
• No on-chain operations or wallets are required throughout the process; it’s simple and straightforward.

3. How to Place an Order?

• Select a prediction market (e.g., a specific match).
• Choose an outcome direction (Home Win / Draw / Away Win).
• Enter the amount and confirm the order after checking the estimated execution price, shares, and fees in the confirmation popup.
• The minimum order amount is 2 USDT, using an "all or nothing" policy: if the entire order cannot be filled, a full refund will be issued with no fees charged.
• You can sell anytime before settlement to take profits or hold until settlement.

4. How to Profit?

• If your prediction is correct: each share settles at 1 USDT; profit = 1 − purchase price.
• If your prediction is incorrect: the share value becomes 0.

• Prices fluctuate in real-time based on market supply and demand, allowing you to "buy low and sell high" to close positions early without waiting for final settlement.

5. When Does the Market Settle?

• Each market has clear settlement rules and conditions.
• After the event ends, the third-party arbitration mechanism automatically finalizes the result and triggers the settlement process.
• Winning outcome shares are paid out at 1 USDT per share (excluding fees), automatically credited to your spot account.

6. Can I Sell Anytime?

• Note: Once the market closes, trading is no longer possible, and you must wait for final settlement.

7. How Is the Price Determined?

• Prices are determined by real-time supply and demand: the more people buy a particular outcome, the higher its price; conversely, the price is lower.
• Prices fluctuate between 0–1 USDT (0–100¢), corresponding to an implied probability of 0–100%.

8. Are There Any Fees for Trading?

• USDT is deducted from your spot account, and the actual amount is displayed once in the order popup.
• No fees are charged for failed orders.

9. Why Are the Execution Price and Displayed Price Different / Why Does a Trade Fail?

• Slippage: The displayed price on the page is the current best order price and only applies to small orders. For large orders, multiple order levels are filled sequentially, causing the average execution price to increase—this is slippage. It is more pronounced with lower liquidity and larger orders.
• Trade Failure / Refund: If the current market liquidity is insufficient and the entire order cannot be filled, a full refund is issued with no fees charged under the "all or nothing" policy.
• Difficulty Selling Near Settlement: As the event nears completion and the outcome becomes clearer, losing positions may find no buyers willing to take them over.
• Shares Reset to Zero After Settlement: After market closure, losing positions are cleared according to the rules, which may result in shares showing as zero.

10. Risk Warning

• Principal Loss: Incorrect predictions can result in loss of your invested principal.
• Market Volatility: You may experience unrealized losses.
• Settlement Delays: Disputed events may cause settlement delays.
