Investors are withdrawing from Binance and its US-based sister company following their recent troubles with American regulators. Market depth on the US sister exchange has dropped by almost 80% since the US Securities and Exchange Commission (SEC) filed a lawsuit against both companies last week.

The SEC accused Binance boss Changpeng Zhao of commingling customer funds through a "web of deceit." Market makers have left Binance US en masse, causing the exchange's liquidity to plummet. The decline on Coinbase and Binance has been less severe.
