From a structural point of view, BNB Bank follows a standard reflection-token model on BNB Chain where a percentage of transaction fees is redistributed to holders in USDT. The key idea is that every transaction contributes to a shared reward pool, and distribution is proportional to holdings. The system itself doesn’t require an external revenue source in the traditional sense — it operates entirely on internal trading activity. That means the “fuel” of the system is volume. When volume is high, the reward pool grows faster and payouts feel more consistent. When volume decreases, the entire reward structure naturally scales down.
