Someone contacted you promising guaranteed returns. Crypto scams change their look but repeat the same formula. Here are the types and the defences.
Crypto scams keep changing their names and looks, but the skeleton is nearly identical. They lure you with big gains, pay out small profits at first to win trust, get you to put in more, and finally block withdrawals or vanish. Scammers favour crypto because a blockchain transfer is extremely hard to reverse once sent. That makes prevention almost the only real defence. Knowing the tactics in advance trains you to recognise the formula.
The most common type is a pitch promising high returns. Typical versions are self-styled experts in group chats calling out coins, or a fake exchange or app that simply inflates numbers on the screen. The profits look real, but the moment you try to withdraw, one excuse after another blocks you.
Many scams impersonate exchange support, wallet help desks, investigators or celebrities. They claim your account has a problem and send you to a fake site, ask you to install a remote-control app so they can help, or get you to type in your recovery phrase. A genuine exchange or wallet developer will never ask for your recovery phrase or private key. Links in search ads or messages often differ from the official site by a letter or two, so get into the habit of typing official addresses yourself or using bookmarks.
Some scams start with someone you meet online who builds a friendship over a long period and then suggests investing. They avoid the subject of money at first, then introduce a platform they use once trust is built and propose growing money together. Be wary if they avoid video calls, keep postponing meeting, or steer conversations toward money. The deeper the emotional bond, the more easily a victim sets doubts aside, and that is exactly what this tactic exploits.
There are pump-and-dump schemes that drive a price up quickly and secretly sell into the rise, and rug pulls where a team collects money and disappears. Another growing tactic uses free-token giveaways to get you to connect your wallet, then gains permission to move your assets with a single signature. If coins of unknown origin show up in your wallet, connecting to sell or trade them may itself be the trap. As a rule, do not approve any signature request unless you have read what it allows.
If you realise you have been scammed, speed matters more than embarrassment. If the money passed through an exchange, tell its support team immediately and ask them to act on the related accounts, then report to the police cybercrime channel. Keep transfer records, conversations, the other party's accounts and wallet addresses, and take screenshots rather than deleting anything. Recovery services that approach you offering to get the money back are often a second scam, so refuse any that ask for fees up front. Check the police and financial regulators' official guidance for reporting procedures and help lines.
Most scams are filtered out by a few principles. The key is to be the one who verifies, not the one being promised returns. Virtual asset businesses operating in Korea must register with the financial authorities, so if you have never heard of an exchange, check whether it appears on the list of registered businesses the regulators publish.
Scammers never give you time. A chance available only today, a sign-up limited to a few people, a warning that your account will be frozen unless you send money now: any pressure to hurry is a warning sign in itself. Genuine opportunities do not vanish if you wait a day or two. Simply explaining the offer, exactly as presented, to family or someone you trust before deciding is enough to avoid many scams.
