Have you ever worried about the security of your crypto assets? Honestly, in the first half of 2025, hundreds of millions of dollars have already been lost to hackers worldwide. But most of these incidents could actually be prevented—if you know how hackers attack, you can better protect yourself.

The methods hackers use to steal coins are mainly these: phishing links that prompt you to enter your private key, malware secretly recording your actions, impersonating customer service to scam sensitive information, exploiting wallet vulnerabilities or weak passwords to gain access, and man-in-the-middle attacks stealing data on insecure networks. It sounds scary, but defending against these threats isn't that complicated.

**Choosing the right wallet is crucial**

Hardware wallets (like Ledger, Trezor) are the safest choice because private keys are stored completely offline, making it impossible for hackers to access them. Mobile app wallets are convenient but carry higher risks, suitable only for small amounts of pocket money. The standard approach for large funds is: keep the bulk in cold wallets, and only keep transaction amounts in hot wallets. If possible, diversify assets across multiple wallets—don't put all your eggs in one basket.

**Multi-layer protection is essential**

Enable two-factor authentication (2FA) on exchange accounts and wallets, but avoid using SMS verification—SIM swapping is too common. Using hardware security keys (like YubiKey) provides real robust protection. If you're managing large sums, you can also enable multi-signature mechanisms, where multiple private keys are required to authorize any transfer. This way, even if one key is compromised, it won't be enough to steal your funds.

Good protection means hackers will have to look elsewhere. Spending time on this is worth it.
