Answer: It's true that a bank can do fractional banking with 10% reserves, but that doesn't necessarily mean that a CEX (cryptocurrency exchange) can't store users' funds safely. In fact, many CEXs have implemented a variety of security measures such as multi-signature wallets, cold storage, and two-factor authentication to ensure that users' funds are secure and protected from theft or loss. Additionally, many CEXs are also insured, meaning that if a hack or other incident were to occur, users would be able to receive compensation for their losses. Therefore, while it is important to take all necessary precautions when storing funds, CEXs can be a safe and secure option for users to store their funds.
