Binance co-founder Changpeng Zhao, better known as CZ, said CoinEx’s recently announced shutdown differs from previous crypto exchange collapses because the Chinese-rooted platform guaranteed that users could withdraw their assets. Zhao noted that some exchanges closing during the recent crypto downturn at least allowed withdrawals, contrasting that outcome with QuadrigaCX, the Canadian crypto exchange that went bankrupt in 2019 and left customer funds trapped, U.Today reported.
