Sebastián Marset, the Uruguayan drug trafficker dubbed the “modern Pablo Escobar,” was captured in Bolivia on March 13 and is now in U.S. custody, accused of laundering millions of people through crypto networks. The case sparked a joint investigation between Bolivia’s Special Anti-Narcotics Force (FELCN) and the US Drug Enforcement Administration, who met in Washington this week to coordinate their next actions against his alleged financial empire.
The question is not whether cryptography can be used for criminal purposes. Obviously, it is possible; Cryptocurrency laundering volumes reached $82 billion in 2025, according to blockchain intelligence firm Chainalysis, up from $10 billion in 2020.
The real question is whether using crypto actually gives criminals a tracking advantage over cash. This case definitely answers that: it’s not.

Cryptocurrency laundering: what American and Bolivian investigators really discovered
Marset built a reputation as one of South America’s most elusive traffickers, evading capture through multiple identity changes and cross-border movements while allegedly running a continent-wide cocaine ring.
In Paraguay, prosecutors named him as a central figure in A Ultranza Py, one of the country’s largest organized crime investigations, which targeted drug networks transporting cocaine and money laundering proceeds through shell companies and real estate.
What made this latest investigation different was where the financial trail led. Mirko Sokol, general commander of Bolivia’s police, confirmed that intelligence showed Marset was transacting “primarily in cryptocurrencies, rather than physical currency.” An unsealed indictment describes a scheme using “couriers and tokens to secretly deliver illicit currencies in bulk, typically in euros,” a hybrid model mixing old-fashioned cash smuggling and digital asset transfers.
Bolivia’s drug enforcement czar Ernesto Justiniano told local media that investigators were monitoring “money laundering, particularly companies that received funds through cryptocurrencies,” alongside investigations into the diversion of chemicals linked to drug production. The detail is missing from most headlines: the crypto trail did not hide Marset’s network. This helped map it.
What Blockchain Transparency Really Means and Why Criminals Keep Overlooking It
Think of the Bitcoin blockchain as a permanent public receipt book that records every transaction ever made and that no one can erase. Every time Bitcoin moves from one wallet to another, that transfer is recorded forever, visible to anyone with the appropriate tools. Cash left in an alley leaves no trace. A Bitcoin transfer always does.
This is where blockchain analytics comes in. Companies like Chainalysis create software that reads this giant public ledger of receipts and looks for patterns, the same way a forensic accountant might trace money through a network of shell companies, except the ledger is already public and the entries can’t be changed. When investigators suspect a wallet belongs to a criminal network, they can trace every coin that touched it, back and forth in time.
Although Bitcoin is getting a lot of attention, it has not played the safe-haven role many expected. In my opinion, there are several reasons for this.
First, Bitcoin lacks privacy. Transactions can be monitored and potentially controlled, which is why central banks do not seek to hold them.… pic.twitter.com/j78NJdvrOw

The reason Bitcoin’s traceability surprises criminals is a widely held myth: cryptography equals anonymity. This is not the case. Bitcoin is pseudonymous, meaning transactions are linked to wallet addresses rather than names, but wallet addresses can be linked to real-world identities as soon as they touch a regulated exchange, bank account, or even the wallet of a known associate.
That’s the trap. You can move Bitcoin through twenty wallets, but if even one of those wallets is connected to a KYC-verified exchange account, investigators can often work backwards to track you down. For a more in-depth look at how exchange compliance shapes this landscape, this article on regulatory risks on crypto exchanges explains the mechanisms well.
