Common Crypto Scams and Red Flags
Schemes promising high or guaranteed returns are the single clearest warning sign.

In their consumer warning, the EU's supervisory authorities note that fraud and misleading offers are common in crypto and that lost funds are rarely recovered. The schemes look different on the surface but rely on the same basic mechanics: urgency, trust, and a payment that cannot be reversed.
Four recurring patterns
- Fake trading platforms that display a fabricated portfolio with rising value, but where withdrawals are always blocked by new fees.
- Romance and friendship scams where the relationship is built over weeks before the investment is proposed.
- Fake support and fake regulator contacts who ask for your seed phrase, remote access to your computer, or a 'verification' transfer.
- Recovery scams that target people who have already lost money and demand payment upfront.
Concrete red flags
- Promised, guaranteed or improbably high returns, often expressed per day or per week.
- Time pressure: the offer is only valid today, or your account will be closed if you don't act now.
- Contact initiated by a stranger via social media, a dating app or a messaging service.
- Requests to install remote-access software or hand over codes, passwords or your seed phrase.
- Company details that cannot be found with any authority, or a name resembling a known provider's.
- Withdrawals that work for small amounts but are blocked once the sum grows larger.
If you have already been affected
Stop making any further payments, save screenshots, transaction identifiers and all communication, contact your bank if payment was made from an account or card, and file a police report. Stay especially vigilant afterwards: details of victims circulate further, and that is when recovery scams typically appear.
A legitimate party will never ask for your seed phrase – not under any circumstance, for any reason.

EU Authorities Warn of Limited Consumer Protection for Certain Crypto-Assets
The European supervisory authorities have issued a joint warning that many crypto-assets are high-risk products and that consumers often lack the protection that applies to regulated financial services. Here is how the warning should be read – without exaggeration.
Private Keys, Seed Phrases and Wallets
Your wallet does not store coins – it stores keys. Here we explain the difference between a private and a public key, what a seed phrase is, how the storage options differ, and the most common mistakes.
Centralised or Decentralised Exchange?
The difference comes down to who holds the assets and who you can hold accountable. This guide covers how the two models work, how their risks differ, and what you should check before using either of them.
