Security & Wallets

Short answer: your crypto is only as safe as your recovery phrase and your habits. Keep long-term holdings in a wallet where you control the keys, keep the recovery phrase offline and never typed into a website, and treat every message that creates urgency as an attack until you have verified it through a channel you chose yourself.

Who it’s for: anyone holding crypto at any level. Experienced traders still lose money to scams they were sure they would spot, because the patterns keep changing while the target stays the same.

Where does crypto actually get stolen?

Almost never by breaking the cryptography. Losses come from the gap between the technology and the person using it. The most common route is phishing: a fake login page, a fake wallet extension, or a message that looks like it came from a platform you use. Next comes social engineering, where someone builds a relationship over weeks before asking for a “test transaction” or a seed phrase recovery. Clipboard malware quietly replaces the address you copied with the attacker’s own. SIM swaps take over your phone number and then your SMS-based two-factor codes. Fake support accounts work the direct message channels of every platform. Approval scams persuade you to sign a transaction that hands over spending rights on your wallet, which stays valid until you revoke it. Exchange failures and freezes sit in a different category: nothing was hacked, but your balance was a claim on a company that stopped paying. Each route has a defence, and none of them is a complicated one.

How should you store a long-term holding?

The pattern is simple. The more control you hold, the more responsibility you carry, and the two cannot be separated. A hardware wallet does not make you safe on its own. If you photograph the recovery phrase, store it in a password manager, or type it into a support chat, the device is decoration. Write the phrase on paper or metal, keep it somewhere you would keep a passport, and accept that losing it means losing the coins. A short test withdrawal, sent and confirmed before a large deposit, is the cheapest insurance in this category.

Which habits make you a hard target?

• Use an authenticator app or a hardware key for two-factor authentication. SMS codes can be intercepted through a SIM swap, and that path is used constantly.
• Never enter a recovery phrase anywhere except the device that generated it. No legitimate support agent, giveaway, or website will ask for it.
• Reach platforms by typing the address or using a bookmark. Search results and adverts are a normal delivery route for phishing pages.
• Verify the address on your screen, not just the one you copied. Clipboard malware depends on you not looking.
• Treat urgency as a signal. Real platforms do not need your answer in five minutes, and pressure is the oldest tool in the scam toolkit.
• Revoke old token approvals on wallets you have used for years. Approval scams stay open until they are closed.
• Separate holdings. Money you trade can sit on a platform, and money you keep should not.
• Run one small withdrawal end to end before you trust a new platform with a large balance.

• FBI Internet Crime Report (IC3): complaint data that shows how much of the loss is social, not technical.
