Centralized exchanges (CEXs) like Binance or Coinbase are convenient but may pose security risks. They hold your private keys, which means you do not have complete control over your assets. Attacks, bankruptcies, or regulatory issues can lead to loss of money. 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 funds. While 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.
