• Binance will take the final 9 numeric digits of the last Bitcoin block hash value after 23:59:00 (UTC) on the specified day of the promotion period as the winning number.
• A user’s Unique Identifier (UID) contains 9 digits at most. If any UID contains less than 9 digits, “0” will be added in front of the first digit until we have 9 digits in total.
  • For example, assume that the UID is 35283019, the adjusted UID will be 035283019.
• Binance will then use the winning number to match the UIDs from the first digit onwards. Users whose UIDs have the most consecutive identical digits will win the reward.
• If the number of matches exceeds the number of winners, we will then further select winners based on their UIDs in ascending order. Please note: The earlier the account registration time, the smaller the UID number.
  • For example, assume that the last Bitcoin block hash value on the last day of this promotion period is “00000000000000000002569464ba67df545a925485824615faa1fc0b8313fe7c”. Removing the letters from the hash value gives us a string of numbers “00000000000000000002569464675459254858246151083137”. The winning number is “151083137”.
  • Comparing the 9 digits of all UIDs. If a UID matches the last 9 digits of the winning number “151083137”, the user will be the winner.
• Users whose UIDs have more consecutive digits that are consistent with the winning number sequence will be prioritized.
  • By analogy, if a UID does not match the last 7th to 9th consecutive digits, but is consistent with the other 6 consecutive digits in the winning number sequence, the user will be the winner, and so on.
  • Using the above winning number “151083137” as an example, if we matched 2 UIDs using 3 consecutive digits in the winning number sequence (“041283190” and “032183126”), but as there can only be 1 winner, we will select the winner by arranging their UIDs in ascending order. Therefore, UID “032183126” will win.
