Protect Private Keys and Mnemonic Phrases: Never share your mnemonic phrases with anyone, as they are the key to accessing your crypto assets. Once leaked, assets may be stolen. Maintain different credentials for each service to avoid password reuse, choose longer and more complex passwords, and change them regularly.

Choose a Secure Wallet: Hot wallets (online wallets) are convenient for transactions but have relatively lower security; cold wallets (such as hardware wallets) store private keys offline and offer higher security. It is recommended to choose a suitable wallet based on your needs and risk tolerance, or use a combination of hot and cold wallets.

Beware of Phishing: Phishing is a common attack method in the cryptocurrency field, where attackers deceive users into revealing sensitive information through fake websites, emails, messages, etc. Carefully check website domains, email senders, and links, and avoid clicking on suspicious links or disclosing sensitive information.
