Cryptocurrency scams cost European victims hundreds of millions of euros every year. The perpetrators behind these operations are sophisticated, well-resourced, and highly skilled at making fraudulent platforms and investment opportunities appear completely legitimate. Understanding the warning signs before you transfer any funds is the most effective form of protection available.
Based on the cases we investigate at CRE Global, here are the five warning signs that appear most consistently across every type of cryptocurrency fraud.
Warning Sign 1 — Guaranteed Returns and Unrealistic Profits
No legitimate investment of any kind can guarantee returns. This is a fundamental principle of financial markets, and it applies equally to cryptocurrency. If a platform, individual, or investment manager is promising you fixed daily, weekly, or monthly returns — particularly returns that are significantly higher than traditional investments — treat this as an immediate red flag.
The specific figures vary, but fraudulent platforms commonly promise returns of 10%, 20%, or even higher per month. In reality, these returns are either fabricated on a fake dashboard or funded by new investor deposits in a classic Ponzi structure. At some point, withdrawals are blocked, communication ceases, and the funds disappear.
A legitimate investment opportunity will always clearly communicate risk. If risk is never mentioned, that absence alone should concern you.
Warning Sign 2 — Pressure To Act Quickly
Urgency is one of the most powerful psychological tools in a fraudster’s arsenal. You may be told that an investment window is closing, that a special rate is only available for the next 24 hours, or that other investors are competing for the same opportunity. This pressure is deliberately engineered to prevent you from pausing, researching, or consulting with anyone before transferring funds.
Legitimate investment platforms and financial services firms do not pressure clients into immediate decisions. Any person or platform that creates artificial urgency around a cryptocurrency investment should be treated with extreme suspicion. Take the time you need, conduct your own research, and consult an independent financial advisor before committing any funds.
Warning Sign 3 — Difficulty Withdrawing Funds
One of the most reliable indicators of a fraudulent cryptocurrency platform is the inability to withdraw your funds. This often appears in a number of forms — withdrawal requests are delayed indefinitely, additional fees or taxes must be paid before a withdrawal can be processed, or technical issues are cited as the reason funds cannot be released.
This tactic is particularly cruel because it often occurs after a victim has already made multiple deposits and sees a significant balance on their account. That balance exists only on the fraudulent platform’s interface — the underlying funds have typically been moved the moment they were deposited.
If you encounter any resistance, delay, or additional payment demand when attempting to withdraw cryptocurrency from a platform, stop all activity immediately and seek specialist advice.
Warning Sign 4 — Unverifiable Company and Regulatory Information
Every legitimate financial services firm operating in Europe is required to be registered with and regulated by the relevant national financial authority. Before depositing any funds on a cryptocurrency platform, verify the following independently through official sources: the company’s registered name and registration number, the regulatory body it claims to be authorised by, the names and verifiable professional backgrounds of the individuals involved, and a physical address that can be confirmed.
Fraudulent platforms frequently fabricate regulatory credentials, clone the identities of legitimate firms, and use impressive-sounding names and professional-looking websites to create an illusion of legitimacy. If a firm’s regulatory status cannot be independently verified through official channels, do not proceed.
Warning Sign 5 — Unsolicited Contact and Romance-Based Approaches
A significant and growing proportion of cryptocurrency fraud begins with unsolicited contact — through social media, messaging applications, dating platforms, or even accidental message fraud where the fraudster pretends to have contacted you by mistake. Over days or weeks, a relationship of trust is carefully constructed before the investment opportunity is introduced.
This approach — known as pig butchering — is one of the most psychologically damaging forms of cryptocurrency fraud because victims feel a genuine personal connection to the person who ultimately defrauds them. The conversation is scripted, the persona is fabricated, and the investment platform is entirely controlled by the fraud operation.
If someone you have never met in person is introducing you to a cryptocurrency investment opportunity — regardless of how genuine the relationship feels — treat this as a serious warning sign and seek independent advice before taking any action.
What To Do If You Recognise These Signs
If you are currently in a situation where one or more of these warning signs apply, stop all further transactions immediately and do not make any additional payments.
