Quantus (QTC) Deposit and Trading Campaign — Enjoy 0 Maker Fees and Share Up to 25 QTC in Rewards

Dear Users,

To thank our users for their continued support, BigONE is launching the “Quantus (QTC) Deposit and Trading Campaign — Enjoy 0 Maker Fees and Share Up to 25 QTC in Rewards.” The campaign details are as follows:

Campaign Period:
14 October 2026 at 18:00 to 24 October 2026 at 18:00 (GMT 8)

• Campaign 1: Enjoy 0 Maker Fees on QTC/USDT

During the campaign, users who place maker orders on the QTC/USDT spot trading pair will enjoy 0 maker trading fees.

Fees will initially be charged at the standard rate and refunded to users’ funding accounts in a lump sum after the campaign ends.

• Campaign 2: Deposit QTC and Earn Rewards

1. First-Time Deposit Reward

Users who make their first QTC deposit to BigONE from an external address during the campaign and achieve a cumulative net deposit of at least 1 QTC during the campaign will receive a 0.01 QTC reward.

A total of 200 rewards are available and will be distributed on a first-come, first-served basis to eligible users. Each user may receive this reward only once. Users must still meet the minimum net deposit requirement at the end of the campaign to qualify.

2. Deposit and Hold QTC to Share 20 QTC

During the campaign, users who deposit QTC to BigONE from an external address and meet both of the following requirements can share a 20 QTC reward pool in proportion to their average daily eligible QTC holdings:

• Achieve a cumulative net deposit of at least 1 QTC during the campaign.
• Maintain eligible holdings for at least 3 days during the campaign.

Each user's reward will be calculated as follows:

User's reward = (User's average daily eligible QTC holdings ÷ Total average daily eligible QTC holdings of all eligible users) × 20 QTC

The maximum reward per user is 1 QTC. Any amount exceeding an individual user's cap will be redistributed among other eligible users in proportion to their holdings. If all eligible users reach the cap, any remaining rewards will not be distributed.

Eligible holdings are defined as the total available QTC balance across a user's BigONE spot and funding accounts.

Daily holdings will be determined based on account snapshots taken at 00:00 (GMT 8) each day. If a user's eligible holdings are greater than 0 QTC at the time of the snapshot, that day will count as one eligible holding day.

Average daily eligible holdings will be calculated using the holdings recorded in each daily snapshot during the campaign. Snapshots showing no holdings will be counted as zero.

• Campaign 3: Trade QTC to Share 8 QTC

Users whose cumulative eligible trading volume on BigONE's QTC/USDT spot trading pair reaches at least 1,000 USDT during the campaign can share an 8 QTC reward pool in proportion to their eligible trading volume.

Each user's reward will be calculated as follows:

User's reward = (User's eligible trading volume ÷ Total eligible trading volume of all eligible users) × 8 QTC

Note: Maker trading volume is excluded from eligible trading volume.
