Guest: Ilan Zimmer
Let’s break this down.
In this episode of Fraudology, I’m joined by Ilan Zimmer, Director of Payments Risk Management at Coinbase. Ilan spends his days thinking about one of the toughest environments for fraud prevention right now: cryptocurrency platforms.
And if you work in fraud, you already know this space has some unique challenges.
Because here’s what’s actually happening.
Cryptocurrency systems were built around decentralization, pseudonymity, and fast-moving financial transfers. Those features are powerful innovations. But they also create a different set of risks when it comes to scams and financial crime.
Once funds move through a blockchain transaction, recovering them can be extremely difficult. Which means the entire fraud prevention strategy shifts upstream. The focus becomes identifying scams earlier and stopping victims before the payment is finalized.
In this conversation, Ilan and I dig into the mechanics of crypto scam prevention, how organized scam rings operate globally, and why collaboration across banks, telecom providers, and crypto platforms is becoming essential.
Here is what that crypto scam prevention challenge means in practice:
- cryptocurrency fraud risks increasing across digital asset platforms
- organized crypto scam rings operating across international networks
- anonymous crypto fraud challenges complicating investigation and recovery
- financial ecosystem collaboration becoming essential for victim protection
What you’ll hear in this episode
- How crypto scam prevention works inside cryptocurrency platforms
- Why Australia crypto scams have become a major international concern
- How scam networks can be linked to human trafficking operations
- Why collaboration between banks, telcos, and exchanges is critical

Episode notes & key takeaways
Crypto scam prevention requires earlier detection than traditional fraud
At first glance, cryptocurrency fraud might look similar to other forms of financial crime. A victim sends money to a scammer and the funds disappear.
But the mechanics are very different.
In traditional banking systems, fraudulent transfers can sometimes be reversed or investigated through intermediary institutions. Cryptocurrency transactions, however, are often irreversible once confirmed on the blockchain.
Operational indicators may include:
- scam detection in digital assets identifying suspicious wallet activity
- crypto exchange fraud controls monitoring transactions before confirmation
- stopping scam payments before funds leave the platform
- account security in crypto platforms preventing account compromise
Because of this, crypto scam prevention relies heavily on early detection and user education.
Organized scam networks operate across international borders
Another theme discussed in the episode is the transnational nature of many cryptocurrency scams. Fraud groups frequently operate across multiple countries and jurisdictions.
These networks often combine social engineering, phishing, and investment scams to convince victims to transfer funds into cryptocurrency.
Operational indicators may include:
- organized crypto scam rings coordinating across international networks
- transnational scam prevention requiring cross-border investigations
- scammer psychology exploiting confusion and lack of crypto knowledge
- global scam fighting partnerships coordinating enforcement efforts
One important insight Ilan shares is that many scams succeed not because victims are greedy, but because they are misled or confused. That distinction matters when designing prevention strategies.
Collaboration across financial ecosystems is critical
The conversation also highlights the importance of collaboration between different sectors of the financial ecosystem. Banks, telecom providers, and crypto exchanges often see different parts of the same fraud scheme.
When those organizations share intelligence, it becomes easier to disrupt scam operations before victims lose money.
Operational indicators may include:
- bank and telco scam collaboration identifying scam infrastructure
- financial ecosystem collaboration sharing fraud intelligence
- payments risk management in crypto platforms monitoring suspicious activity
- victim protection in crypto through coordinated intervention
Without that cooperation, fraud networks can move quickly between platforms and jurisdictions.
Protecting users in crypto requires education and stronger controls
The final takeaway from this episode is that crypto platforms must balance open financial innovation with strong user protection.
As cryptocurrency adoption grows, new users may not fully understand how irreversible transactions work or how common certain scams have become.
Operational indicators may include:
- protect users from crypto scams through proactive warnings
- Coinbase fraud prevention programs focused on user safety
- anonymous crypto fraud challenges requiring behavioral monitoring
- fraud prevention in cryptocurrency combining education and technology
And this is the broader point Ilan and I discuss throughout the episode.
Stopping crypto scams isn’t just about technology. It’s about building systems that protect users before fraud happens.
