Let me calculate how much money the exchange earns from monthly transaction fees, only including BTC spot and contract transaction fees. I'm scaring you!!! Binance BTC/USDT and BTC/USDC trading pairs 1. Transaction amount Daily average trading volume of spot goods: 3 billion US dollars. Daily trading volume of the contract: 30 billion US dollars. Monthly days: 30 days. Handling fee: For spot goods: Maker (pending orders) 0.1%, Taker (eating orders) 0.1%, with an average of 0.075% (considering VIP user discounts). Contract: Maker 0.02%，Taker 0.04%， Take an average of 0.03% (due to low contract rates and a high proportion of VIP users). 2. Revenue from spot trading fees Monthly transaction volume of handling fee income: 3 billion US dollars x 30 days=90 billion US dollars. Handling fee: 0.075% (i.e. 0.00075). Monthly fee income: 90 billion x 0.075%=67.5 million US dollars=67.5 million US dollars. 3. Contract transaction fee income Monthly transaction volume: $30 billion x 30 days=$900 billion. Service fee: 0.03% (i.e. 0.0003). Monthly fee income: 900 billion x 0.03%=270 million US dollars=270 million US dollars. 4. Total fee income Spot handling fee: 67.5 million US dollars. Contract handling fee: 270 million US dollars. Total: 67.5 million+270 million=337.5 million US dollars=337.5 million US dollars. OKX accounts for about one-third of Binance's revenue, with only BTC transaction fee income exceeding $100 million per month.
