Is cryptocurrency safe?

It depends on which risk is meant. The core technology of the largest cryptocurrencies has held up well for more than a decade. People still lose money in crypto every day, mostly through price falls, failed companies, their own errors and fraud.

Is the technology itself safe?

The bitcoin network has run since January 2009 without an attacker rewriting its ledger. The cryptography that guards each holder's coins has not been broken. The same is broadly true of other large networks.

Smaller networks are weaker, and the apps and companies built on top of any network are weaker still. That is where most hacks happen.

Where do people lose money?

The risks are separate, and each works differently:

• Price. Crypto prices swing far more than those of stocks or currencies. Bitcoin has fallen by more than 75% from a peak more than once, and many smaller coins have gone to zero.
• Platforms. An exchange or lender holding customers' coins can fail or be robbed. The 2022 collapse of FTX is the best-known case.
• Custody mistakes. People who hold their own coins can lose them by misplacing a seed phrase, the list of words that backs up a wallet, or by sending funds to a wrong address.
• Scams. The FBI said in April 2026 that its complaint center recorded more than $11 billion in reported losses involving cryptocurrency for 2025. See the most common crypto scams.
• Code bugs. Programs that hold funds on a blockchain can contain flaws that attackers exploit.

What protections exist?

Fewer than most people expect. In the United States, the Federal Deposit Insurance Corporation says its cover applies to deposits at insured banks and not to crypto assets or the failure of a crypto company. The Securities Investor Protection Corporation, which steps in when a brokerage fails, says unregistered digital asset securities are not protected. More detail is in is crypto insured.

Payments are also final. The Federal Trade Commission notes that crypto payments typically cannot be reversed and lack the dispute rights that come with credit cards.

Some protections do apply. Fraud is a crime whatever the payment method. Licensed exchanges must check customers' identities and follow anti-money-laundering rules. Because most ledgers are public, investigators can sometimes trace and seize stolen funds. Rules differ by country and state and change over time.

Does it matter how crypto is held?

Yes. Coins left on an exchange depend on that company staying solvent and honest. Coins held in a personal wallet depend on the owner keeping the keys safe, with nobody to call if they are lost. The trade-off is set out in custodial vs non-custodial wallets.

Neither choice removes price risk. Cryptoweek explains how these risks work and does not advise on whether to own crypto.
