According to the announcement from Binance, the exchange will support the SpaceX (SPCXB) airdrop for MarsCoin (MARSCOIN) holders and the Invesco QQQ Trust (QQQB) airdrop for 牛来 holders. The distribution includes two reward components. First, Binance will distribute the SPCXB and QQQB tokens allocated on-chain by the respective projects to eligible MARSCOIN and 牛来 holders. Second, Binance will allocate 30% of MARSCOIN and 牛来 spot trading fees as additional rewards, to be distributed in the form of SPCXB and QQQB respectively until further notice. Both reward components will use the same valid holding calculation method. Binance said it will take one random snapshot per day of users’ MARSCOIN and 牛来 holdings throughout each calendar month, and only daily holdings exceeding 10,000 tokens will count as valid holdings for each token. Monthly valid holdings will be calculated as the sum of each user’s valid daily holdings during the month, and rewards will be distributed based on each user’s share of total valid holdings among eligible users. MARSCOIN and 牛来 holdings will be calculated separately.

Binance said snapshots will include MARSCOIN and 牛来 holdings and liabilities in Spot Accounts, Funding Accounts, Margin Accounts and Simple Earn Flexible Accounts. Undistributed interest payments will not be included, and tokens pending deposit or withdrawal at the time of the snapshot will not count toward a user’s balance. MARSCOIN and 牛来 liabilities from Margin or Crypto Loans will not be eligible for the airdrop, and users with net liabilities will need to return the equivalent amount of SPCXB or QQQB airdropped. Holdings on Binance Alpha will not be included in the snapshot. Eligible holdings will be calculated starting from September 2026, with the first distribution in early October 2026. Both reward components will follow the same monthly cycle and will be fully distributed by the beginning of the following month. Binance said deposits and withdrawals of MARSCOIN and 牛来 will not be impacted, and Spot, Margin, Futures trading and Binance Earn services will continue without interruption during the airdrop. Users must complete account verification and be from an eligible jurisdiction to qualify, and reward eligibility remains subject to applicable product and jurisdictional restrictions.
