Crypto or Scam? How to Spot a Ponzi Disguised as Bitcoin

5 min readUpdated 28 October 2026

Cryptocurrency is real, and so is the risk of losing money through crypto trading. Alongside the real market sit schemes that borrow the language of Bitcoin and artificial intelligence to sell a promise that cannot be kept.

This guide is for anyone who has been invited to put money into a crypto or “AI trading” platform. It explains how a Ponzi scheme works, what happened with CBEX in 2025, and the checks that tell the two apart. It is not investment advice.

How a Ponzi scheme works

A Ponzi scheme pays early members with money from newer members, not from real profits. To keep paying, it needs a steady flow of new deposits. When that flow slows, withdrawals stop, the scheme collapses and most members lose money.

Many Nigerians remember MMM, which froze members’ accounts in December 2016. The idea has not changed. The packaging has. Words like “arbitrage”, “bots” and “AI” make the promised profit sound technical and harder to question.

What happened with CBEX

CBEX, short for Crypto Bridge Exchange, presented itself as an AI-powered trading platform. According to the EFCC, its promoters promised returns of up to 100 percent.

In April 2025, users found they could not withdraw. Reports say the platform demanded “verification” fees to release their money, then stopped paying out altogether. The authorities responded:

• The Securities and Exchange Commission (SEC) Nigeria said neither CBEX nor its affiliates had ever been registered to operate as a digital assets exchange or take investments from the public in Nigeria.
• The EFCC said it was investigating with help from Interpol, obtained a court order to arrest promoters and declared several people wanted.
• In June 2025, the SEC warned again after reports that the platform had resurfaced and was charging users fees to recover their money.

Estimates of the total loss vary widely and have not been confirmed. What is clear is that a platform many people trusted with their money was never registered to take it.

What real crypto trading looks like

Crypto trading means buying and selling coins such as Bitcoin and Ether, hoping to profit from price changes. Prices move sharply both ways, and experienced traders lose money too.

• Spot trading is buying a coin and selling it later, hopefully at a higher price.
• Futures trading is betting on price movements, often with borrowed money, which magnifies losses as well as gains.
• Arbitrage is buying on one exchange and selling on another to profit from small price differences. The margins are thin, and other traders close the gaps quickly.

On a genuine platform, you can see the coins you own and the trades you make, the company is identifiable, and withdrawals follow published rules. Your balance rises and falls with the market, not in a smooth line upwards.

Why “AI trading” is the new disguise

Trading software exists, and large firms use it. But no software removes the risk from a volatile market, and none can guarantee daily or weekly profits. For a clearer picture of what AI does well, see our look at the AI tools Nigerians are actually using.

Fake AI platforms usually have the same features:

• A dashboard that shows your balance growing every day. The operator controls those numbers.
• Membership levels or “VIP” tiers that pay more if you deposit more.
• Bonuses for bringing in friends and family.

Small early withdrawals often work. That is part of the design, because paying a few people builds trust.

Red flags to watch for

• Guaranteed or fixed returns. Real markets do not pay a set percentage every day, week or month.
• Returns that depend on recruiting. If you earn more by bringing in others, new members’ money is likely paying old ones.
• Fees to withdraw your own money. “Verification”, “tax” or “activation” fees are a classic sign that a scheme is running out of money.
• No identifiable company. No registered address, no named management and no registration with the SEC.
• Pressure to act fast. “Last chance” messages are there to stop you checking.
• Celebrity or influencer promotion. A famous face proves nothing. Under the Investments and Securities Act 2025, promoting a Ponzi scheme is itself an offence.

Checks to make before you send money

1. Check registration with the SEC. The Investments and Securities Act 2025 treats digital assets as securities and places digital asset operators under the SEC. Look the platform up on sec.gov.ng, which lists registered operators. If it is not there, treat it as unregistered.
2. Do not accept other papers as a licence. CAC registration or a SCUML certificate is not permission to take investments from the public. The EFCC made this point after CBEX.
3. Search for warnings. Search the name with “SEC”, “EFCC” or “scam”, and trust news reports over members’ testimonials.
4. Ask how the money is made. If the answer is “AI” or “arbitrage” with no detail you can verify, walk away.
5. Never pay to withdraw. A legitimate platform publishes its fees and does not ask you to send fresh money before you can take out your own.

Before any investment you do not fully understand, speak to a licensed financial adviser.

If you have already sent money

Stop depositing, even if the platform says one more payment will release your funds, and do not recruit anyone to make up your losses. Save screenshots of your dashboard, chats, transfer receipts, account numbers and the names of the people who introduced you.

Report it to the EFCC, through its official website or nearest office, and to the SEC Nigeria. Then be careful of anyone who offers to recover your money for a fee. Recovery scams target people who have just lost money, as we explain in our guide to spotting fake alerts and payment scams. Before any future investment, check the platform with the SEC.
