Cryptocurrency investments are lucrative targets for cybercriminals, making it crucial to implement robust security measures. This guide provides essential tips and best practices to protect your crypto assets from cyber attacks and ensure their safety.

Understanding Cyber Threats in Crypto

Common Types of Cyber Attacks:

Hardware Wallets:

2. Enable Two-Factor Authentication (2FA)

Best Practices:
