Binance (CRYPTO: BNB) CEO Changpeng Zhao has said that transaction fees account for 90% of the company's earnings.

In order to provide a cleaner experience, Binance had eliminated all advertisements from the data site CoinMarketCap, which it had purchased in 2020, Zhao says.

"We can turn that back on, that’ll give us $40 million a year. But we don’t need to today," Zhao told TechCrunch. Binance's 2021 income was reportedly $20 billion.
