👉🏻 Recently, #OKX revealed that users lost their assets due to various security issues. Learning the following preventive measures can help you avoid more than 90% of security threats:

  1. Use hardware wallets:
    Utilize hardware wallets like OneKey, Trezor, etc. These wallets offer offline storage, isolating your assets from the internet at a physical level, effectively preventing hacking attacks and network theft. Although they may be relatively cumbersome to use, especially for frequent transactions, they are the safest storage option, especially for large amounts of funds that won't be accessed in the short term.

  2. Enable Two-Factor Authentication (2FA):
    Enable 2FA in both exchange and wallet accounts. This adds an extra layer of security confirmation during account access or asset transfer, preventing unauthorized access.

  3. Safeguard your private keys and mnemonic phrases:
    Private keys are the sole means to access cryptocurrency. Ensure they are not leaked or lost. For wallets holding significant funds, it's best to store private keys offline, either on paper or using a hardware wallet.

  4. Avoid using public Wi-Fi:
    Avoid using public Wi-Fi when conducting cryptocurrency transactions or accessing wallets. Public networks are susceptible to hacking attacks, such as Wi-Fi hotspots in airports or cafes, which are highly likely to be fake.

Connecting to such hotspots exposes all your online activities to potential interception, including decryption of your operations and even plain-text transaction passwords.

  1. Regularly update software:
    Ensure that the exchanges, wallets, and operating systems you use are up-to-date to prevent exploitation of known security vulnerabilities.

  2. Use trusted exchanges and wallets:
    Choose exchanges and wallet service providers with good reputations and security records. Avoid using obscure platforms; while you aim for profits, they might aim to take all your capital.

  3. Beware of phishing and scams:
    Avoid clicking on unfamiliar links or downloading unknown attachments. Ensure that you are accessing the correct official websites.

✨ The most vulnerable areas are Telegram and Twitter. Be cautious of clicking on links sent by strangers, let alone copying them into your wallet to open. Once your wallet's signature or authorization is obtained, your assets could be instantly transferred away.

  1. Utilize multi-signature technology:
    Multi-signature requires multiple signatures to complete transactions, ensuring that even if one private key is stolen, funds cannot be accessed independently.

A common example is multi-signature wallets, which require multiple private key signatures to execute cryptocurrency transactions. Such wallets enhance fund security and control, widely used for both personal and institutional cryptocurrency management.

  1. Employ decentralized storage:
    Avoid storing all funds in one place. Decentralized storage helps mitigate the risk of single-point failures, applicable to both wallets and exchanges.
