The recent asset reserve certificate from KuCoin revealed a decrease of over 25% in their Bitcoin reserves following a lawsuit from the U.S. Department of Justice (DOJ) related to alleged bank acts and money laundering violations. Users withdrew significant amounts of Ethereum (ETH) and stablecoins like Tether (USDT) and USD Coin (USDC) as well. The legal challenges faced by KuCoin involve accusations of non-compliance with financial laws, suspicious fund handling, and violation of regulatory policies by its founders. Despite the situation, the company reassured customers of the safety of their assets.
