# FAQ (Frequently Asked Questions) ## About Entry and Rewards ### **What does the entry fee cover?** The entry fee is the participation fee to enter the challenge. The $10,000 virtual capital used by all participants is provided by the system and unrelated to entry fees. ### **Can I customize my entry amount?** Yes. You can freely choose any amount from $5 to the cap in $5 increments. ### **How does entry amount affect rewards?** Reward = Entry amount × Reward multiplier. For example, $50 entry × 10x = $500 reward. ### **Are entry fees refundable if I fail?** No. Entry fees are non-refundable after challenge failure. ### **When are rewards distributed?** After challenge success, click "Claim Reward" and confirm the on-chain transaction. Rewards are sent to your wallet immediately. *** ## About Challenge Rules ### **Can I participate in multiple challenges simultaneously?** No. Each wallet address can only have 1 active challenge at a time. After your current challenge ends, you can purchase a new one. ### **When does the challenge start?** Immediately after paying the entry fee. The countdown begins and cannot be paused or cancelled. ### **Can I exit a challenge midway?** No. Once started, challenges run until the countdown expires. You can close positions early to lock in profits, but cannot exit the challenge. ### **Why am I profitable but the challenge shows I haven't met the target?** Possible reasons: * Some profits came from trades held under 60 seconds (not counted toward progress) * Single trade profit exceeded 75% cap (excess not counted) * Trading fees offset some gains ### **What qualifies as a "valid trade"?** Trades held for 60 seconds or longer count as valid trades for the "60-second holding rule" requirement. *** ## About Trading and Risk Control ### **Which coins can I trade?** Specific trading pairs and leverage limits are shown in "Rule Details" when selecting a challenge. ### **Are there trading fees during challenges?** Yes. Fees apply to opening and closing positions (see "Rule Details" for specific rates). Fees are deducted from your virtual account equity. ### **What leverage can I use?** Maximum leverage limits are displayed in your challenge details page. Beginners should use low leverage to reduce risk. ### **When will forced liquidation occur?** Forced liquidation occurs when: * Account equity hits drawdown limit (challenge fails) * Challenge expires with open positions remaining * Insufficient margin (virtual capital can also be liquidated) ### **Can I continue trading after hitting the drawdown limit?** No. Once the drawdown limit is hit, the challenge immediately terminates, all positions are force-liquidated, and the challenge is marked as failed. *** ## About Referral Mechanism ### **What are the benefits of inviting friends?** * You: Earn 5% of remaining target for each person invited * Friend: Receives 5% extra time + 10% entry discount ### **How many people can I invite?** Each challenge has a referral limit—see challenge details page. Once the limit is reached, no more invites accepted. ### **When are referral rewards distributed?** Referral rewards settle when your challenge ends. If the challenge fails, referral rewards are not distributed. *** ## About Security and Fairness ### **Is Edge Hour fair?** Yes. All participants use the same $10,000 virtual capital, same rules, and same market prices. Success or failure depends entirely on your trading strategy. ### **Can trading data be verified?** Yes. All trades and settlements are completed on-chain. Anyone can verify trade records and settlement processes. ### **Will people cheat?** We have strict risk control mechanisms: * IP/device fingerprint correlation analysis * Trading behavior pattern recognition * Minimum holding time requirement (60 seconds) * Single trade profit cap (75%) Confirmed cheaters have rewards revoked; serious offenders are address-banned. *** ## Technical Questions ### **Is there trading latency?** DeriW is built on [Arbitrum Orbit Layer 3 network](https://docs.deriw.com/deriw-chain/about-deriw-chain), providing extremely low latency trading experience approaching that of centralized exchanges. ### **Do I need to pay gas fees?** Trading on DeriW is zero-gas. However, claiming rewards may require a small gas fee for the on-chain transaction. ### **What if the network lags?** If challenge failure results from technical issues, we'll manually review. If confirmed, we may provide full refunds or re-challenge opportunities.
