Idea 1 of 4
Slow down the pitch.
A persuasive story is not enough evidence to invest. Promises of high returns with little or no risk, pressure to act quickly and secret strategies deserve scrutiny. Pause before the pitch turns into a payment. Source 1.
No single checklist proves an offer safe. A polished app, a familiar name or a friend’s apparent success can be part of the story. Check who is asking, what is being offered and where the money would actually go.
High return, no risk?
Ask what could go wrong and how the claim can be checked.
Must act today?
Urgency gives you less time to investigate.
Where does it go?
Verify the recipient and account independently.
Only their screenshots?
Look for evidence beyond the promoter’s own records.
These questions identify concerns; they do not certify an investment or accuse a named business.
How does a Ponzi scheme work?
How does a pump and dump work?
A reason to hurry is a reason to slow the decision down.
Idea 2 of 4
A statement is not independent proof.
The Madoff case shows why the source of a record matters. The SEC Inspector General found that independent trading verification had not been completed during the examined SEC investigations. Source 4.
For 31 January 2005, one feeder-fund statement showed about $2.5 billion of S&P 100 equities. The report compared that with DTC records showing less than $18 million of those equities in Madoff’s DTC account. These are the specific records the report examined, not an estimate of every asset or every customer’s loss.
The practical lesson is to obtain evidence through an independently verified institution, rather than accepting another document supplied by the same person making the claim.
The OIG said a third-party inquiry could have exposed the mismatch.
What is a relationship or “pig butchering” scam?
Records supplied by the promoter are claims to verify, not final proof.
Idea 3 of 4
Verify the person, firm and contact.
Check both the record and the identity using it. FINRA’s BrokerCheck and the SEC’s Investment Adviser Public Disclosure database help research people and firms. Read registration, employment and disclosure information. Source 6.
Scammers can copy a registered professional’s name or alter a genuine-looking report. Start from the official database yourself, then compare the firm, identifiers and independently obtained contact details.
Registration is not a guarantee against fraud. Some offerings also have legitimate registration exemptions. An absent search result needs further investigation rather than an automatic verdict about every kind of investment.
Check the identity
Match the name and registration identifiers.
Check the affiliation
Read the firm and disclosure records.
Verify the channel
Use independently obtained contact details.
The person messaging you must match the professional and firm you independently researched.
What does a registration check leave unanswered?
What if you suspect a scam or already sent money?
Research independently. Match the identity. Never treat registration as a safety seal.
Idea 4 of 4
Practice spotting the warning signs.
Use a fictional message to practice. An online contact becomes friendly, promises high returns with no risk and shows profits in an app. They say you must pay a fee today before withdrawing.
Select only the warning signs described in that message. The exercise counts your selections; it does not investigate a firm or calculate a probability of fraud.
Which warning signs can you identify?
Fictional example · practiceNo signs selected. That is not a safety verdict; check the claims and identity independently.
This practice uses the fictional message above. Zero selections do not clear an offer, and a count does not establish fraud. It does not search official registers, inspect a company, send a report or determine whether money can be recovered.

Review your takeaway card and the learning path
- Pause the pitch. High-return promises and urgency deserve scrutiny.
- Verify the evidence. Screenshots and statements are claims to check.
- Match the identity. A real registration record can be copied by an impostor.
- Act through official channels. Stop sending money to a suspected scammer and report without expecting guaranteed recovery.

Sources checked 16 October 2026. The Madoff figures are a dated, specific comparison from the SEC OIG report, not a total-loss or current-recovery estimate. The practice message is fictional. Warning signs guide further checks; they do not prove a named business fraudulent or certify an offer safe. Reporting channels here are US examples; use the appropriate local authority elsewhere.
