Binance Exchange Ecological Scenario
BNB has two functions:
1. Use BNB to trade and receive discounts on transaction fees
2. Lock BNB and slow down the flow rate of BNB. In order to obtain transaction fee discounts, users need to lock a certain amount of BNB.
3. If a user holds more than 500 BNB positions, the commission rate for inviting friends will be increased to 40%.
