Crypto exchanges Binance, Coinbase join West Africa scam sweep that flagged $11 million

Authorities in Ghana and Nigeria joined technology companies in a coordinated crackdown on West African scam networks. The operation focused on cryptocurrency investment fraud affecting people in the United States, the United Kingdom, and elsewhere. The U.K. National Crime Agency hosted it, and the U.S. Department of Justice called it the first joint operation of its kind focused on West Africa.

Police arrested 19 people near Accra and seized 303 electronic devices. Nigerian authorities arrested nine more. Crypto exchanges Coinbase and Binance, along with Chainalysis, Elliptic, and TRM Labs, traced funds and supplied intelligence. Meta removed more than 3.7 million accounts, pages, and groups linked to impersonation scams.

The operation also identified 117 trafficking victims in Ghana awaiting repatriation to Nigeria. Private-sector partners flagged more than $11 million for possible freezing, and investigators received leads on over 30 suspected scam centers. Officials also reported cryptocurrency seizures, but did not disclose their value or assets.

Cryptocurrency investment fraud is a scam that presents a supposed digital-asset investment as a path to profits. The victim may believe they are dealing with a legitimate adviser, company, celebrity, or friend. The goal is to make the victim transfer money or cryptocurrency to the scammers.

A typical scheme creates confidence first. Scammers can use social-media impersonation, convincing messages, fake investment dashboards, or promises of unusually strong returns. They may show invented profits and request additional deposits, fees, or taxes before allowing a withdrawal. Once funds are sent, the victim may lose access or face more demands. These specific tactics are not detailed in the article, but they are established features of such fraud.

The operation targeted networks accused of this kind of crime. Coinbase said it identified more than 65 active scam victims and prevented over $415,000 in potential losses. Meta removed accounts and pages that appeared to target Americans and Britons through impersonation.

The operation was large because it combined criminal arrests, financial intelligence, trafficking investigations, and platform enforcement. Authorities arrested 28 people in total: 19 near Accra in Ghana and nine in Nigeria. Ghanaian authorities also seized 303 electronic devices during the arrests.

The NCA reported 117 trafficking victims in Ghana who were awaiting repatriation to Nigeria. Investigators received leads on more than 30 suspected scam centers. Private-sector partners identified more than $11 million in funds that could potentially be frozen. That figure describes flagged funds, not confirmed money recovered.

Meta removed more than 3.7 million Facebook and Instagram accounts, pages, and groups. Most appeared to target people in the United States and United Kingdom through impersonation. Officials also reported cryptocurrency seizures, but the article gives no value for those seizures and does not identify the assets involved.

When funds are flagged for a possible freeze, investigators or private companies have identified transactions or balances that may be connected to suspected crime. The next step could involve an exchange, financial institution, or authority restricting movement while the case is examined. A flag is therefore an investigative lead or preservation opportunity.

The article says private-sector partners identified more than $11 million in funds that could be frozen. Crypto exchanges and blockchain-analysis companies helped trace illicit funds and support asset freezes. This work can prevent suspected funds from moving, but it does not establish that every flagged dollar came from crime.

A recovery is different because it means money or assets were actually seized, returned, or otherwise obtained by authorities or victims. The article explicitly says the $11 million represented funds flagged for a possible freeze, not confirmed recoveries. It separately mentions cryptocurrency seizures without disclosing their value or the assets involved.

Binance and Coinbase participated as crypto-exchange partners. Coinbase said it traced illicit funds, supported asset freezes, and provided intelligence to investigators. It also identified more than 65 active scam victims and prevented more than $415,000 in potential losses. The article does not specify a separate Binance action.

Chainalysis, Elliptic, and TRM Labs were the blockchain-analysis partners. They helped examine cryptocurrency activity. TRM Labs said it exposed a large peer-to-peer laundering network. The article does not assign separate public actions to Chainalysis or Elliptic. Meta removed more than 3.7 million Facebook and Instagram accounts, pages, and groups involved in apparent impersonation.

Law-enforcement agencies in Ghana and Nigeria arrested 28 people and seized 303 devices in Ghana. The NCA hosted the joint operation and reported 117 trafficking victims. The DOJ described the effort as the first joint operation focused on West Africa, while investigators received leads on more than 30 suspected scam centers.

Blockchain-analysis companies examine transaction records to map how cryptocurrency moves between digital addresses, exchanges, and other services. They can connect related transactions, identify patterns, and flag flows that appear linked to suspected criminal activity. This is possible because blockchain transaction histories are recorded and can be analyzed. The article confirms tracing and intelligence work, but does not explain each company’s technical method.

In this operation, Coinbase said it helped trace illicit funds, support asset freezes, and provide intelligence to investigators. Blockchain firms Chainalysis, Elliptic, and TRM Labs participated. TRM Labs said it exposed a large peer-to-peer laundering network. Such findings can give exchanges or law enforcement a basis to investigate a wallet or request that funds be restricted.

A trace does not automatically prove a crime or guarantee recovery. Partners flagged more than $11 million for possible freezing, but the article stresses that this was not confirmed recovery. Officials reported crypto seizures without giving their value or identifying the assets.

These crimes can form a connected chain. Social-media impersonation gives scammers a believable identity and a way to reach targets. Investment fraud then persuades people to send funds. Laundering moves those proceeds through other accounts, wallets, or peer-to-peer networks, making the money harder to follow. The article links all three elements in the networks targeted by the operation.

Meta removed more than 3.7 million Facebook and Instagram accounts, pages, and groups, many apparently impersonating people or organizations while targeting Americans and Britons. TRM Labs said it exposed a large peer-to-peer laundering network. Authorities also arrested people at a suspected center near Accra and seized 303 electronic devices.

The human cost extended beyond online victims. The NCA identified 117 trafficking victims in Ghana who were awaiting repatriation to Nigeria. The operation also produced leads on over 30 suspected scam centers. Together, these findings show why investigators combined platform action, financial tracing, arrests, and trafficking work.
