How to Spot a Crypto Scam: 12 Red Flags That Repeat Every Cycle

By Coinporta Editorial· 7 min read· Jun 2026

Most crypto scams share the same tells: guaranteed returns, urgency, unsolicited messages, fake endorsements, and requests for your seed phrase. Here are 12 red flags.

Most crypto scams share the same handful of tells: guaranteed or sky-high returns, pressure to act now, unsolicited messages, fake celebrity endorsements, and any request for your seed phrase. If an opportunity has several of these, it is almost certainly a scam. Real investing is never urgent, guaranteed, or secret.

12 red flags of a crypto scam

  • Guaranteed or risk-free returns. No real investment can promise this.
  • Urgency. A countdown or "limited spots" exists to stop you thinking.
  • Unsolicited contact. A stranger messaging you first is a warning, not an opportunity.
  • Fake endorsements. Cloned posts from Elon Musk and other names promoting a coin.
  • Any request for your seed phrase or private keys.
  • "Send 1 coin, get 2 back" giveaways. The money never comes back.
  • Upfront fees to unlock or withdraw your supposed profits.
  • Cloned exchange or wallet websites with a slightly wrong address.
  • An anonymous team and no real whitepaper.
  • Romance that pivots to a can't-lose investment, known as pig butchering.
  • Secret AI bots or insiders that always win.
  • Pressure to recruit friends, which signals a pyramid scheme.

Security firms like McAfee and Kaspersky report the same patterns cycle after cycle.

The single clearest rule: no legitimate service will ever ask for your seed phrase. Not an exchange, not a wallet, not "support." The request itself is the scam.

Common crypto scam types

  • Phishing sites that copy a real exchange to steal your login.
  • Giveaway scams promising to double any coins you send.
  • Investment and romance scams that build trust, then drain you.
  • Fake apps and exchanges that take deposits and vanish.
  • Rug pulls, where a new coin's team sells everything and disappears.
  • Recovery scams that target people who were already scammed.

How to protect yourself

  • Never share your seed phrase, and never type it into a website.
  • Bookmark real sites and check the address before logging in.
  • Ignore unsolicited offers, however legitimate they look.
  • Turn on 2FA and use an authenticator app, not SMS.
  • Move savings to your own wallet so a hacked exchange account cannot drain everything.

If you are setting up self-custody, start with what a seed phrase is and how to move crypto to a wallet.

What to do if you have been scammed

Stop sending money immediately, screenshot everything, and report it to your local fraud authority and the platform involved. Be wary of anyone who contacts you offering to recover your funds for a fee. That is almost always a second scam aimed at the same victim.

A guarantee. No real investment offers risk-free or guaranteed returns. Pair that with urgency or an unsolicited message and it is a scam.
