Traders are pulling billions of dollars from Binance as problems plaguing the world’s largest crypto exchange continue to mount.

The Commodity Futures Trading Commission on 27 March sued Binance, alleging the exchange operated illegally in the US and violated rules designed to prevent illicit financial activity. Last week, Binance announced it would charge fees on spot bitcoin trading again after cutting them to zero last summer. It also had to temporarily suspend spot trading for hours while it fixed a software error.
