Binance, the world's largest cryptocurrency exchange, has reportedly maintained a significant presence in China despite the country's ban on cryptocurrency trading in 2021. Internal figures suggest that Chinese users traded $90 billion worth of cryptocurrency assets in a single month, making China Binance's biggest market. Binance is also said to collaborate with Chinese law enforcement to detect potential criminal activities. In June, the SEC filed a lawsuit against Binance and its founder, accusing them of operating illegally and misusing customer funds.
