Not announcing the rules in advance is to let you grind, the more you grind, the more chances you have.

Binance's airdrop rules are like the college entrance examination, emphasizing fairness and transparency. The rules of the college entrance examination are public, and everyone strives for a good score through hard work. Although the competition is fierce, it is a 'reasonable competition.' This airdrop event by Binance also follows similar principles, announcing the points rules only 2 hours before the airdrop to avoid meaningless competition of early point accumulation, ensuring that every participant competes on equal footing. Just as everyone is studying hard before the college entrance examination, the rules are set, and the final score is determined by effort. In this event, Binance not only maintained fairness but also leveraged the role of BNB and the activity of the BNB chain to promote trading and user engagement on the platform. BNB, as an important component of the Binance ecosystem, plays a role in facilitating trading, paying transaction fees, and enhancing platform activity, while the activity of the BNB chain provides strong support for these activities. Although the points rules were not announced in advance, the final airdrop rewards are based on fair competition; those who can earn rewards through effort under this mechanism are the true lucky ones. By implementing these fair competition rules, Binance allows everyone to strive for opportunities within a reasonable framework, while also increasing platform interactivity and user participation.
