How this scam works

In this scam, high-pressure salespeople cold-call or email you to buy shares, often in obscure or worthless companies, using urgency and false promises, then make it impossible to sell or disappear with your money.

Crypto and investment scams promise high or guaranteed returns with little risk, usually through fake platforms that display staged gains. Small test withdrawals build trust before you are pushed to invest more, then blocked from withdrawing behind endless "fees" and "taxes".

In short, the giveaway is usually simple: An unsolicited cold call pushing you to buy shares quickly for big guaranteed gains. Hang up and verify the firm with your financial regulator before any investment.

Scammers rotate tactics constantly, the same operation may also run the Pension Scam and the Forex Trading Scam. See the full Crypto & Investment Scams guides hub, or test a suspicious message with the scam checker.

How to spot this scam

What the message looks like

Example pattern, not a real report
Example pattern: 'This stock is about to soar, but you must buy today. We guarantee strong returns. How much can you invest right now?'

This is a fictional, anonymised example used to illustrate the pattern. It is not a verified real message, and any names are used only to show how the scam typically reads.

What gives it away: An unsolicited cold call pushing you to buy shares quickly for big guaranteed gains.

How do I verify an investment firm?
Check your national financial regulator's register and warning lists, and get independent regulated advice. Be wary of any unsolicited approach.
I bought shares from a cold caller. What now?
