Criminals Shift from Bitcoin to Stablecoins as Illicit Crypto Use Changes

Criminals are moving away from Bitcoin and leaning harder on stablecoins, and that says a lot about where illicit crypto use is headed. River reports criminals prefer stablecoins over Bitcoin as illicit crypto use shifts dramatically, and the shift comes down to one brutal fact: if you’re moving stolen funds, you don’t want them melting in value while you wait to cash out.

• Illicit activity is shifting: stablecoins are becoming the preferred rail for criminal transfers
• Bitcoin is a clumsy crime tool: volatility makes it a poor fit for laundering
• Tracing is improving: blockchain analytics and tighter compliance are squeezing bad actors
• Stablecoins cut both ways: useful for payments, but also useful for fraud, ransomware, and laundering

River’s finding cuts against the tired old talking point that Bitcoin is the default playground for cybercriminals. That line has always been sloppy at best and dishonest at worst. Bitcoin is transparent by design. Every transaction is recorded on a public blockchain, meaning it’s visible to anyone with the right tools. That doesn’t make Bitcoin unusable for illicit activity, but it does make it a pretty lousy hiding place compared with cash, shell companies, and more opaque financial rails.

The real reason stablecoins are more attractive is simple: stability. A stablecoin is designed to track something like the US dollar, so it doesn’t swing wildly while funds are being moved. For legitimate users, that’s useful because it makes payments and settlements predictable. For criminals, it’s useful for the exact same reason. If you’re trying to launder money, run a scam, or move ransom payments, the last thing you want is a 10% price drop while you’re waiting to off-ramp.

That’s where Bitcoin loses its edge for this kind of activity. Bitcoin’s volatility is a feature for traders and long-term holders, but for illicit actors it can be a self-inflicted tax. If your “business model” depends on keeping value intact over a short period, BTC can be a messy instrument. Useful? Absolutely. Convenient for crime? Much less so than people think.

River’s report also reflects a broader reality: criminal networks adapt fast. As exchanges tighten compliance, sanctions screening gets better, and blockchain analytics firms improve their tracing tools, bad actors migrate to whatever works best. Today, that increasingly means stablecoins. They’re faster, more liquid, and easier to move across borders than many traditional payment methods. In plain English, liquidity means how easily an asset can be converted into cash or another asset. Criminals love liquidity because it makes cashing out less painful. Shocking, really.

But here’s the part that deserves a little honesty instead of crypto tribal nonsense: stablecoins are not “good,” and Bitcoin is not “bad.” They’re tools. Stablecoins are becoming essential for trading, treasury management, remittances, payroll, and everyday payments in places where banking is expensive, slow, or politically unreliable. That same utility also makes them attractive to fraud rings, ransomware crews, and laundering networks. The rail doesn’t care who’s riding it. Humans are the problem.

Because stablecoins run on public blockchains, they also leave a trail. That matters. Every on-chain movement is recorded, which means investigators, compliance teams, and analytics firms can often follow flows far better than they could with physical cash or older offshore methods. “On-chain” simply means recorded on the blockchain and visible to the network. That transparency is one reason enforcement has become more effective over time.

There’s also another wrinkle: some stablecoins can be frozen or blacklisted by their issuers. That’s a compliance feature, and it’s a big reason regulators are paying so much attention to the sector. It can also be a drawback for people who care about censorship resistance and financial sovereignty. The same mechanism that helps stop criminals can also give issuers serious power over user funds. For cypherpunks, that’s not a bug. It’s the whole problem.

Bitcoin, by contrast, remains the hardest money in the room, not the easiest laundering tool. It is public enough to be traceable, volatile enough to be risky for illicit transfers, and liquid enough to be broadly useful without being ideal for stealth. That’s why the “Bitcoin is for crime” narrative is increasingly outdated. If anything, the rise of stablecoins in illicit finance shows Bitcoin is being pushed toward its more natural role as a reserve asset and settlement layer, while stablecoins handle the transactional grease.

That said, stablecoins are not some clean moral upgrade. They are the new favorite tool for plenty of real-world use cases, but they also create new choke points. Regulators are unlikely to ignore that. Expect more pressure on stablecoin issuers, exchanges, and off-ramps, because those are the easiest places to apply control. The blockchain itself may be open, but the bridges to and from the banking system are where the knives come out.

The darker side of all this is that open financial systems are, by design, neutral. They don’t ask whether the person using them is a freelancer in Argentina trying to get paid, or a fraudster trying to move stolen funds before sunrise. That neutrality is a feature of decentralized systems, not a flaw. But it also means the bad actors will always try to exploit the same rails honest users depend on. No amount of marketing fluff changes that.

Key takeaways and questions:

• Why are criminals preferring stablecoins over Bitcoin?
  Stablecoins hold their value far better during transfers. Bitcoin’s volatility creates extra risk for anyone trying to move illicit funds without losing money to price swings.

• Does this mean stablecoins are more dangerous than Bitcoin?
  Not inherently. Stablecoins are simply more practical for certain kinds of abuse because they combine price stability, speed, and easy cross-border transfer.

• Is Bitcoin still used in illicit finance?
  Yes, but less than many people assume. Its public ledger and price volatility make it a poor fit for the most common laundering and concealment tactics.

• Why does blockchain transparency matter?
  Because it lets investigators and compliance teams trace funds on-chain, often making crypto crime easier to track than cash-based crime.

• What does this mean for stablecoin regulation?
  More scrutiny is coming. Issuers, exchanges, and payment platforms are likely to face heavier compliance pressure as regulators focus on the rails criminals actually use.

• What does this mean for Bitcoin’s role?
  It reinforces Bitcoin’s position as a settlement asset and store of value, not the preferred tool for everyday illicit movement of funds.

The shift from Bitcoin to stablecoins in illicit crypto use is not a win for anyone except maybe the people who enjoy pretending all digital assets are the same. They’re not. Bitcoin remains the most credible monetary asset in the space, but it’s not a universal payment rail and it’s not the favorite toy of every scammer with a laptop. Stablecoins are proving more useful for real commerce, but that same usefulness also makes them more attractive to criminals. That’s the tradeoff. Welcome to open finance: powerful, messy, and impossible to sanitize with a press release.
