Crypto Wallet Security Basics: How to Protect Your Coins

Crypto gives you something traditional banking does not: direct control over your money. The flip side is that you are also responsible for protecting it. Americans reported $11.366 billion in losses involving cryptocurrency to the FBI's Internet Crime Complaint Center in 2025, up 22% from 2024. Many of those losses came from scams that tricked people into sending funds, not from sophisticated hacks.

The good news is that a handful of habits go a long way. Here are the crypto wallet security basics every U.S. user should know.

Why Crypto Security Is Different

When something goes wrong with a credit card, you can usually dispute the charge. Crypto works differently. The Federal Trade Commission points out that cryptocurrency payments typically are not reversible and do not come with the legal protections that credit and debit cards offer. Crypto held in accounts is also not insured by the government the way dollars in an FDIC-insured bank account are.

The FTC also warns that if you lose the password to your wallet, send crypto to the wrong person, or your wallet is compromised, you are likely to find that no one can step in to help you recover your funds.

Know Your Wallet Types

A crypto wallet stores the keys that let you access and move your coins. The FTC notes that a wallet can be online, on your computer or on an external device. In practice, most people use one of these:

• Custodial accounts. An exchange or app holds the keys for you. They are convenient, but you depend on the company's security and solvency.
• Software wallets. Apps on your phone or computer where you control the keys. They are easy to use but exposed to malware and phishing if your device is compromised.
• Hardware wallets. Small physical devices that keep keys offline. They add a strong layer of protection for larger, long-term holdings.

Many people use a combination: a small amount in a convenient wallet for everyday activity and the rest in more secure storage.

Protect Your Seed Phrase Above All

If you control your own wallet, you will usually be given a recovery phrase, often 12 or 24 words. Anyone who has that phrase can take your funds. Treat it like the master key to your money:

• Write it down on paper or another durable material and store it somewhere safe.
• Never type it into a website, share it in a chat or store it in a photo or cloud note.
• No legitimate company, support agent or government agency will ever ask for it.

Lock Down Your Accounts

For exchange and app accounts, basic account hygiene matters:

• Use a long, unique password for every crypto account, ideally managed by a password manager.
• Turn on two-factor authentication, preferably with an authenticator app or security key rather than text messages.
• Keep your phone and computer operating systems and apps updated.
• Use withdrawal address allowlists if your exchange offers them.
• Double-check every wallet address before sending. Payments to the wrong address usually cannot be reversed.

Recognize the Most Common Scams

The FBI's 2025 IC3 report found that cryptocurrency investment fraud alone accounted for $7.228 billion in losses across 61,559 complaints. Crypto ATM and kiosk scams produced another 13,460 complaints and $389 million in losses, a 58% jump in losses from 2024. People aged 60 and older reported the largest losses of any age group.

The FTC highlights warning signs that should stop you in your tracks:

• Only scammers demand payment in cryptocurrency. No legitimate business will demand crypto in advance.
• Only scammers guarantee profits or big returns.
• Never mix online dating and investment advice. If a new online friend wants to teach you to invest in crypto, it is a scam.
• Impersonators may pose as your bank, a tech company or a government agency and urge you to move money into crypto "for safekeeping."

Be wary of "recovery" services too. The IC3 report counted 10,516 recovery scam complaints and $1.4 billion in losses, often from people who had already been scammed once.

What to Do If Something Goes Wrong

Act quickly. Contact the exchange or wallet provider you used, change passwords, and report the incident. The FTC recommends reporting crypto fraud to ReportFraud.ftc.gov, the CFTC, the SEC and the FBI's Internet Crime Complaint Center at ic3.gov. Recovery is not guaranteed, but reports help investigators track scammers.
