Changpeng Zhao, 46 years, comes from a family that immigrated to Vancouver, Canada from China after the Tianmen protests. He studied computer science at McGill University and worked for Bloomberg Tradebook. In 2017 he started Binance as a cryptocurrency firm. In the same year China banned cryptocurrency. In March 2023 the Commodity Futures Trading Commission sued Binance saying that the Binance exchange operated illegally in the US and violated rules on illicit financial activity. This WSJ report says traders are withdrawing billions of dollars from Binance as problems affecting the world's largest crypto exchange increase. Overall WSJ says Binance holds $63.2 billion in the exchange's publicly disclosed wallets. Regulators are concerned about bank runs of the kind that affected FTX, another crypto currency firm.
