Forex and Crypto Scam Red Flags: Ponzi Pools, Fake Funds and Licence Checks

Investment scammers rarely look scary. Most show up as a friendly new contact, a chat group where someone posts profits every day, or a page using a famous brand’s logo. This article collects the red flags that come up again and again in Thailand and elsewhere, explains how each trick works, works out why “5% a month, guaranteed” can’t be true, and shows how to check a broker’s licence yourself before you send a single baht.

Ten red flags

You don’t need to see all ten. One is enough to stop and check. Good scammers make everything else look right: a polished website, a company certificate, reviews, and people in the group swearing they withdrew without trouble.

1. Guaranteed profits or fixed monthly returns

Forex, gold and crypto go up and down all the time, and every real trading system has losing stretches. The more risk a system takes, the deeper those stretches go. Anyone who says “profit every month” or “your capital is safe” is promising something trading can’t deliver. If the numbers really are the same every month, it usually means they don’t come from trading.

Why “5% a month, guaranteed” can’t be true

Work out what 5% a month compounds to. The formula is capital × 1.05^months.

Period	Multiplier	10,000 baht becomes	Total gain
1 year (12 months)	1.05¹² = 1.796	17,959 baht	+79.6%
3 years (36 months)	1.05³⁶ = 5.792	57,918 baht	+479%
5 years (60 months)	1.05⁶⁰ = 18.68	186,792 baht	+1,768%

Over 10 years the multiplier is 1.05¹²⁰ ≈ 349, so one million baht would become about 349 million. Someone who could really do this wouldn’t need money from strangers. Compounding their own money, or borrowing from a bank, would make them far richer.

What does a real system look like? In How to compound position size we simulated a system known to have an edge (it wins 35% of trades, and a winner makes twice what a loser costs), risking 1% per trade. After 200 trades, 10,000 ended at 10,829, a gain of just 8.3%. Along the way the median maximum drawdown was 17%, and there was still a 35.8% chance of finishing below the starting balance. That is a system with an edge, and it still swings like this. For more on losing runs, see How many losses in a row are normal.

A very high return that is smooth every month isn’t proof of skill. It’s a sign the numbers may not come from the market.

A very smooth equity curve can also come from a Grid or Martingale system that wins almost every trade until one long trend wipes the account out in one go. See how in Grid, Martingale and recovery trades.

2. Pooled “fund management” and Ponzi schemes

A common pitch is “let our team trade for you and collect a monthly dividend”. Your money leaves an account in your own name and goes into their pool. All you see is a number in an app or a file they send you. Some of these pools do trade, lose and hide it. Others never trade at all and use new deposits to pay earlier investors. That second kind is a Ponzi scheme, named after Charles Ponzi, who ran one in the United States in the 1920s.

If you earn a commission for bringing in new people, or there are member tiers based on how many people you recruit, the scheme’s main income is new members’ money, not trading. The person who invited you may be a victim who doesn’t know it yet.

A Ponzi’s cash flow: where it breaks

We simulated a made-up pool (not a real case) with simple rules.

1. New deposits are 1 million baht in month 1 and grow 25% a month until month 10. Then new people run out and new deposits shrink 20% a month.
2. The pool promises 5% a month on all the principal members have put in.
3. 20% of each new deposit goes to recruiter commissions and to the operator.
4. There is no trading profit at all. Everything paid out comes from deposits.
5. From the month that payouts exceed new deposits, some members get nervous and ask for their principal back, 5% of total principal per month.

Month 15 as an example: principal at the start of the month is 50.85 million, so the 5% payout is 2.54 million. Only 2.44 million of new money comes in, so withdrawals start: another 2.54 million of principal. Total money out is 5.08 million, while money in after the 20% commission is 1.95 million.

What the model shows:

• In months 1–14 the cash in the pool rises every month, peaking at 27.82 million. Anyone looking only at that would think the pool is healthy. But at that point it owes members 50.85 million of principal, so the cash it actually holds covers only about 55% of what it owes.
• New deposits fall from month 11, yet the dividend bill keeps growing until about month 15, because it is based on accumulated principal, not on new money.
• In month 22 the cash goes negative and payments stop. At the end of month 21 there was 1.47 million left, while the pool still owed members 43.46 million of principal.
• Over the 22 months, 61.01 million came in, 12.20 million went to commissions and the operator, and 51.28 million was paid out as dividends and returned principal (61.01 − 12.20 − 51.28 = −2.47, the shortfall in month 22).

Real schemes differ in the numbers, but the structure is the same. A Ponzi doesn’t collapse from bad luck. It collapses from arithmetic: what it owes grows with accumulated principal, while new money would have to grow forever, which it can’t. Early members may get their money back. Late members usually lose almost everything.

3. Pressure and urgency

“This is the last round.” “Only 3 slots left.” “Transfer before midnight.” Urgency is there to stop you thinking or asking anyone. A good investment doesn’t vanish in 24 hours. If you’re being rushed, treat that as a reason to slow down. The biases that push us into bad decisions are covered in Trading biases and psychology.

4. Unlicensed brokers, or licences you can’t verify

Fake brokers often quote a company registration number, show a nice certificate, or claim a licence from a country that’s hard to check. Here’s how to check yourself.

1. Ask which regulator licenses them and for the licence number. If they won’t say, stop there.
2. Go to the regulator’s own website by typing the address yourself. Don’t click a link from the broker’s site or from a chat. Search the register by licence number.
3. Match the company name letter for letter, plus the website domain and contact details listed on the register. Some scammers copy a real firm’s name and number, known as a clone firm. What gives them away is the website and contact details, so only use the contact channels the register lists.
4. Check that the company you’d open an account with is the same company on the register. Some broker groups have several companies in different countries, and foreign clients may be onboarded through a sister company under different rules.
5. Many regulators publish a warning list of unauthorised firms. Search for the name there too.

Examples of regulators with public registers include the UK’s FCA, Australia’s ASIC and Cyprus’s CySEC. They are not equally strict about things like segregating client money, leverage caps and investor compensation. In Thailand, the regulator for securities and digital assets is the SEC (ก.ล.ต.), which publishes lists of licensed businesses and investor alerts on sec.or.th. You can use these to check crypto platforms and people offering investments. On the specific legal position of forex trading for Thai residents, we aren’t legal experts. If you’re unsure, ask the authority directly.

A licence lowers the risk of fraud but does nothing about trading losses, and we don’t recommend any particular broker.

5. You can’t withdraw, or have to pay to withdraw

The clearest sign of a scam is a balance that grows nicely but can’t be withdrawn. Common excuses: you must first pay a “tax”, an “unlock fee”, a “verification fee”, or “top up to the minimum balance”. A legitimate provider deducts its fees from what you withdraw. It doesn’t ask you to send more money to get your own money out.

If you have to send more money to withdraw your own, assume the money in there may no longer exist, and don’t send another baht.

A simple test before depositing a large amount is to deposit a little and try withdrawing it. It won’t catch everything, though. Many Ponzis let small withdrawals through easily to build trust.

6. Fake MT4/MT5 servers and doctored statements

MT4 and MT5 are real software, but the numbers they show come from the provider’s server. If that server belongs to a scammer, it can display any price, profit or balance they like. Fake crypto trading apps work the same way. A balance on screen doesn’t mean the money exists.

Statements sent as images or files are easy to edit. A screenshot with only winning trades, or a curve that rises smoothly without a single red month, deserves suspicion rather than trust.

7. “Recovery” offers after a loss

People who have just lost money are often contacted again by a “recovery team”, a “lawyer” or an “official” who says they can get it back for an upfront fee. Often it’s the same group, or a group that bought a list of victims. Regulators in many countries warn about this repeatedly, and real government agencies don’t message you asking for fees. If you’ve been scammed, contact the bank or platform you paid through as fast as you can, keep the evidence, and report it to the police directly.

8. Romance and “pig butchering” crypto scams

This one starts with a wrong-number message, a dating app or a new social media friend. You chat for weeks and get close. Then they mention they earn from trading crypto or gold and invite you onto an app or site where “a relative works”. At first you see profits and small withdrawals work, so you put in more, until the day you can’t withdraw and are told to pay a “tax” first. The name “pig butchering” comes from fattening a pig before the slaughter.

The simple rule: when someone you’ve never met in person brings up investing, stop there, however long you’ve been talking.

9. Impersonating real brands on social media

Fake pages use the logos, names and photos of real companies or well-known people. They buy ads, make posts dressed up as news, or send a fake admin to your DMs. The page name or domain may differ from the real one by a single letter. Protect yourself by contacting the brand through a website address you type yourself, by not trusting anyone who messages you first, and by remembering that a real admin never asks for your password, OTP code or crypto wallet seed phrase.

Five questions before you send money

1. Is the money in an account in my own name, with a provider I found on a regulator’s register?
2. Does the return they describe include losing periods, or is it too high and too smooth?
3. Does the income come from recruiting people?
4. Am I being rushed?
5. If I lost all of this money, would I be OK?

If you want to start trading yourself, begin on a demo account and step up slowly, as in From demo to a live account, and learn about leverage and stop out first. For any term you’re unsure of, see the glossary.

Common mistakes

• Trusting it because it has paid for months. A Ponzi can pay as long as new money comes in. In the model above, the cash in the pool rose every month for the first 14 months.
• Trusting it because a friend invited you. The friend may earn a commission, or be a victim who doesn’t know it yet. Being close to someone isn’t evidence.
• Checking the licence through a link they sent. The link may lead to a fake site dressed up as the regulator. Type the regulator’s address yourself.
• Paying to unlock a withdrawal. Every payment adds to the loss, and there is never a last one.
• Giving an OTP code or seed phrase to an “official”. Anyone with your seed phrase can move every coin out of your wallet.
• Being too embarrassed to report it. The sooner you tell your bank, the better the chance of stopping further transfers, and reporting helps warn others.
