Crypto scams to avoid: the common ones and the warning signs

Crypto scams take money through fake exchanges, fake support, phishing and fake gains. The common forms, the warning signs and what to do if hit.

Crypto · Updated 2026-10-09 · 1,222 words

Crypto scams are common, fast and hard to reverse. Transfers on a blockchain are final, and many scams work by getting the victim to send coins or share access before they realise what is happening. The methods change, but the pattern is steady: someone creates urgency, offers an easy gain or poses as someone you trust, and then takes what you have.

This guide describes the common types of crypto scam, the warning signs that appear before the money is lost, and what to do if you have already been hit. It is written for anyone who buys, holds or is thinking about trying crypto.

Why crypto scams work

Three features of crypto make scams effective. Transactions are irreversible, so once coins are sent, they are gone. Many people are new and unfamiliar with how wallets and contracts work, so they are easy to confuse. And the market is fast-moving, so scammers can create a sense of urgency that makes careful checking feel like a missed chance.

Crypto also has a reputation for quick gains, which scammers use. A promise of high returns with no risk is the most common sign of a scam in any market.

Fake exchanges and apps

A fake exchange is a website or app that copies a real one. It may use the same logo and similar wording, and it lets you deposit funds and see a balance. When you try to withdraw, you are told you need to pay a fee, verify again or deposit more first. The balance was never real, and the deposit is gone.

Protect yourself by typing the address of the exchange yourself or using a bookmark you made, not a link from a message or an advert. Check the app's publisher on the official app store. Be wary of apps that promote themselves through messages or social media ads.

Fake support and recovery scams

Scammers monitor people who post about lost coins or locked accounts, and they contact them through social media or messaging apps. They pose as support staff from a wallet or exchange and offer to help recover the funds. They ask for your seed phrase, your password or a small payment to start the process. Once they have the seed phrase, they empty the wallet.

Real support staff never ask for your seed phrase or password, and they never contact you first about your account in a private message. A recovery service that asks for a fee to recover lost crypto is almost certainly a scam.

Phishing

Phishing uses fake messages, emails and websites to trick you into entering a seed phrase, a password or a verification code. A message may say your account is locked or that a transaction needs approval, and it links to a page that looks like the real one. Entering your details there gives the scammer access.

No legitimate wallet or exchange will ask you to enter your seed phrase on a website. Check the address carefully, and never enter the seed phrase anywhere except the wallet's own restore screen, on a device you trust.

Rug pulls

A rug pull is when the team behind a new token or project drains its funds and disappears, leaving holders with a worthless coin. The usual pattern is a launch with heavy promotion, a token that rises, and then the team removes the liquidity or sells its large holdings. Holders are left trying to sell into a market with no buyers.

Warning signs include an anonymous team, a small number of wallets holding most of the supply, no independent audit of the contract, locked liquidity that is not actually locked, and promotion that focuses on the price rather than the product.

Pump-and-dump schemes

A pump-and-dump scheme inflates the price of a small coin through coordinated promotion, then sells into the buying. Promoters may use social media, chat groups or paid influencers to create excitement. New buyers arrive at the high price, and the early group sells. The price then collapses.

The signs are a sudden surge in price with no real news, heavy promotion from many accounts at once, and urgency to buy before a supposed announcement. If you did not find the coin yourself, be cautious.

Investment and romance scams

Some scams build a relationship over weeks or months, often through a dating app or social media, then steer the victim into a crypto investment platform. The platform shows large gains on a dashboard, and the victim is encouraged to deposit more. Withdrawals are blocked by fees and delays. These scams are sometimes called pig butchering, because the victim is fattened with apparent gains before the loss.

Be cautious of anyone you have only met online who encourages you to invest, and of any platform that shows fast gains you cannot withdraw.

A worked example: a fake gain

Suppose you join a platform that shows your 5,000 deposit growing to 12,000 over two months. You try to withdraw 4,000 of the gains, but the platform says you must first pay a 10 percent tax, which is 1,200, to a wallet it provides. You pay, and the withdrawal is still not released, and now the platform asks for a further fee.

The dashboard figures were never real. The 12,000 was a number on a screen, and the fees are the scam's way of taking more. You have lost the original 5,000 and the fees you paid. The lesson is that a gain you cannot withdraw is not a gain.

Warning signs

Guaranteed or very high returns. No honest investment guarantees a profit.

Urgency. Pressure to act within hours, or a limited window.

Unsolicited contact. Anyone who contacts you first about money or accounts.

Requests for your seed phrase, password or a verification code.

Requests to pay fees before you can withdraw.

Pressure to keep the matter secret or to move the conversation to a private channel.

Platforms you cannot verify or that are not regulated where you live.

What to do if you have been scammed

Act quickly, because some recovery steps depend on time. Stop sending money. If you gave someone your seed phrase or password, move your remaining coins to a new wallet with a new seed phrase, if you still can. Change the passwords on any account you used and turn on two-factor authentication.

Report the scam to your local police or cybercrime unit, to the financial regulator in your country, and to the platform you used if it is a known exchange. Keep every message, transaction hash and screenshot. Be aware that people who say they can recover lost crypto for a fee are often running a second scam.

Key takeaways

Crypto scams take money through fake exchanges and apps, fake support, phishing, rug pulls, pump-and-dump schemes and investment platforms that show gains you cannot withdraw. Irreversible transactions and fast markets make them effective. Watch for guaranteed returns, urgency, unsolicited contact, requests for your seed phrase and fees before withdrawal. If you have been hit, stop sending, secure what you still have, and report it quickly.

Frequently asked questions

Can a crypto transaction be reversed if I was scammed?

Usually not. Blockchain transfers are final, and most exchanges cannot reverse them once sent. Quick reporting can sometimes help an exchange freeze funds, but it is not guaranteed.

Is it a scam if an app asks me to connect my wallet?

It can be. Connecting a wallet can give a site the ability to request approvals that move your coins. Check what you are approving, and only connect to sites you have verified.

Who should I contact after a scam?

Your local police or cybercrime unit, your financial regulator, and any exchange or platform you used. Keep all the records you have. This guide is for general information, not financial advice. If you have been affected by a scam, seek help from your local authorities.
