Bitunix Event Contract Product Terms

Effective Date: May 13, 2026

I. Important Access Notes (Please Read First)

1.1 Bitunix Event Contract products currently adopt a random open invitation system. Only users who have received a clear invitation from Bitunix are eligible to use this product.

1.2 Even if you have received an invitation, you must not use this product if the laws of your location, nationality, or current jurisdiction prohibit you from participating in such transactions. You are solely responsible for understanding and complying with all applicable laws and regulations in your jurisdiction. Bitunix shall not be liable for any liability or loss arising from your violation of local laws.

1.3 These terms are an integral part of the Bitunix User Agreement. Using Event Contracts means you agree to these terms, the User Agreement, and the Privacy Policy. If you do not agree, please do not use this product.

1.4 We may update these terms as business needs require. Updated terms will be published on the Bitunix Platform. Your continued use of this product will be deemed as acceptance of the update.

II. What are Event Contracts?

An Event Contract is a product that allows you to predict the future price direction of a digital asset (e.g., Bitcoin, Ethereum, etc.). You do not need to actually buy or sell the asset. You only need to pay a premium and choose "Call" or "Put".

• Call Contract (Higher): You believe the price at expiration will be higher than the current price.
• Put Contract (Lower): You believe the price at expiration will be lower than the current price.

The payout amount for each Event Contract is fixed, but the premium you pay will change dynamically based on market conditions, thereby affecting the actual payout ratio.

III. How to Enter into an Event Contract

3.1 You may submit an order through the functionality available on the Bitunix Platform. We do not guarantee to accept every order, nor do we guarantee that any order will be executed.

3.2 When placing an order, you need to select an expiry time (e.g., 5 minutes, 1 hour, etc.). Once selected and submitted, the expiry time cannot be changed.

3.3 Before placing an order, the platform will show you the premium amount and the fixed payout amount for that order. After your confirmation, the system will automatically deduct the corresponding amount of USDT from your Bitunix account.

3.4 USDT is the only settlement currency supported for this product. Please ensure you have sufficient available USDT balance in your account, otherwise you will not be able to place an order.

3.5 We may temporarily disable order placement functionality due to system maintenance, risk control, or other reasons. We will use reasonable efforts to notify you in advance, but we do not guarantee advance notice in every instance. Existing open contracts will not be affected.

IV. Position and Limit Rules

4.1 We will set a maximum number of open (unexpired) contracts that each user may hold simultaneously (the "Open Position Limit"). Orders exceeding this limit will be automatically rejected by the platform. The specific limit value will be shown on the platform.

4.2 Daily Loss Cap: We currently have not set a Daily Loss Cap. However, please note that we reserve the right to set such a cap in the future. If we do so, we will announce the relevant rules in advance. Until then, you are responsible for managing your own daily trading risk.

4.3 Because the payout ratio is dynamically adjusted based on market conditions, the premium and payout amount you receive may vary for different times and different users. The amount shown on the platform at the time of your order will prevail.

V. Settlement Method

After a contract expires, the system will automatically settle it according to the following rules:

1. If you hold a Call contract and the Index Price at expiration is higher than the Strike Price, you will receive the fixed payout amount.
2. If you hold a Put contract and the Index Price at expiration is lower than the Strike Price, you will receive the fixed payout amount.
3. If the Index Price at expiration is equal to the Strike Price, regardless of Call or Put, we will refund the full premium you paid.
4. In all other cases (i.e., wrong direction), you will lose the entire premium and the Settlement Value will be zero.
5. After settlement, the applicable payout amount or refunded premium will be automatically credited to your Bitunix account.

VI. Prohibition of Insider Trading

6.1 You must not use any non-public information that may affect the price or payout calculation of Event Contracts to trade. Such information includes, but is not limited to: system vulnerabilities on the Bitunix Platform, upcoming major announcements, large orders of other users, platform operational decisions, risk control parameter adjustments, etc.

6.2 If we find that you have engaged in insider trading, or if we have reasonable grounds to suspect such conduct, we have the right to take one or more of the following measures:

1. Immediately freeze or restrict your account;
2. Cancel all your open Event Contract orders;
3. Confiscate all profits obtained through insider trading;
4. Permanently prohibit you from using Bitunix Event Contract products;
5. Close your Bitunix account;
6. Report the relevant situation to regulatory or law enforcement authorities.

6.3 If you know or suspect that others are engaging in insider trading, you are welcome to report it through official customer service channels. We will keep the report information strictly confidential.

VII. Risk Warnings

1. Trading Event Contracts involves significant risks. Please fully understand the following before participating:
2. Market Volatility Risk. Digital asset prices are highly volatile and may rise or fall sharply within a short period. You may lose your entire premium due to an incorrect prediction.
3. USDT-Related Risks. This product only uses USDT for trading. USDT is a stablecoin, but its market price may deviate from US$1 (i.e., "de-pegging"). If USDT de-pegs significantly, the USDT you hold may depreciate, and the normal settlement of Event Contracts may also be affected.
4. Liquidity Risk. There may be times when you cannot place or close orders smoothly, for example due to system congestion, network failures, or severe market fluctuations.
5. Technical Risk. Internet failures, cyberattacks, system upgrades, and other force majeure events may cause trading delays, interruptions, or data loss.
6. Regulatory Risk. Your country or region may introduce new laws or regulations at any time that restrict or prohibit Event Contract products. You are responsible for monitoring local policy changes.
7. Invitation System Restriction. Even if you received an invitation, you must not use this product if you are from a restricted jurisdiction. The list of restricted jurisdictions is set out in the Bitunix User Agreement.
8. Important Reminder: You should only trade with funds you can afford to lose. Bitunix does not provide any investment advice. You are solely responsible for making your own investment decisions and bearing all risks.
