Centralized exchanges (CEXs) like Binance or Coinbase are very convenient but can pose security risks. They hold your private keys, meaning you do not have full control over your assets. Attacks, bankruptcies, or regulatory issues can lead to loss of funds. To stay safe, you should only keep a minimal amount of cryptocurrency on exchanges for trading. Transfer the rest to a personal hardware wallet for better control. Enable two-factor authentication (2FA) and use strong passwords to protect your account. Regularly monitor for suspicious activities and withdraw funds immediately after trading. Research the security history of the exchange before depositing money. Although CEXs offer ease of use, prioritizing self-management helps reduce reliance on third parties and enhances your cryptocurrency security in an unpredictable market. Be cautious and proactive.
