All four major cryptocurrency exchanges - Kucoin, Gate, Huobi, and Binance - offer users the opportunity to buy and sell digital assets. However, when it comes to withdrawing funds, only Huobi and Kucoin allow users to do so without completing a Know Your Customer (KYC) process. Gate and Binance both require users to complete KYC before allowing them to withdraw funds. KYC is a process that requires users to provide personal information, such as a copy of a government-issued ID or passport, to verify their identity. This is done to ensure that users are who they say they are and to prevent money laundering and other financial crimes.
