Mysterious Gen Z Drug Kingpin Sentenced to 20 Years for Laundering Millions in Crypto

A young drug trafficker from Generation Z has been sentenced in South Korea to 20 years in prison after the court concluded that he systematically used cryptocurrencies as both a payment method and a money-laundering tool within a large-scale narcotics network with an estimated turnover of $4 million. The verdict was delivered by the Ulsan District Court, where prosecutors detailed how the defendant and his group smuggled drugs into the country via international courier services and sold them through the Telegram messaging app. In addition to the prison sentence, the court imposed a $4.2 million fine. Presiding Judge Park Jeong-hong stated during sentencing that importing drugs through international parcel delivery is extremely difficult for police to detect. According to the judge, this form of crime is spreading rapidly, making exceptionally harsh punishments necessary. He emphasized that such activity is highly antisocial and has serious consequences for society as a whole.

Telegram as a “Drug Supermarket” for the Young According to investigative records, Korean-language Telegram channels have effectively turned into “narcotics department stores,” particularly for young South Koreans. Payments for drugs were primarily made using Bitcoin and other cryptocurrencies. The defendant began selling drugs online as early as March 2020. Over time, he built a network of associates who helped operate multiple parallel sales channels on Telegram. The offerings included synthetic cannabinoids, marijuana, LSD, and methamphetamine, with most of the drugs smuggled in from Vietnam. Cryptocurrencies were used not only to collect payments but also to launder proceeds from criminal activity. Distributors were paid a 10% commission on each successfully completed delivery.

Thousands of “Dead Drop” Deliveries Nationwide The dealer relied on a nationwide network of smaller-scale sellers who carried out so-called “dead drops”—leaving packages of drugs in public places and sending buyers instructions on where to pick them up. Prosecutors revealed that between March 2022 and May 2023 alone, nearly 12,000 deliveries were made this way, involving more than 7,000 kilograms of methamphetamine pills. The court stated that the defendant had created a distribution model that other drug dealers are now copying. According to the judge, this has significantly increased the sophistication and activity of the illegal drug market, effectively mass-producing new addicts and drug-related criminals. In addition to the main defendant, three of his close associates were sentenced to between 30 months and three years in prison, all found guilty of drug distribution and money-laundering offenses.

Telegram Investigation and Limits of Cooperation A year earlier, South Korean authorities launched an investigation into Telegram amid allegations that the platform was being used to distribute illicit content. However, investigators faced major obstacles due to Telegram’s refusal to provide user account data to law enforcement agencies, both domestically and internationally. As a result, the Korea Communications Standard Commission (KCSC) added Telegram to its list of foreign platform partners, enabling it to request the removal of illegal content, including information related to narcotics.

Crypto Regulation Shift and New Money-Laundering Methods At the same time, a significant regulatory shift has taken place. South Korea’s Financial Services Commission (FSC) lifted its ban on corporate investments in cryptocurrencies, a restriction that had previously been justified by concerns over money laundering. The final version of the rules is expected to be published in January or February, with the draft allowing legal entities to invest up to 5% of shareholder equity in cryptocurrencies within the top 20 by market capitalization. Stablecoins are not yet included, with a decision on them to be made later. According to Chainalysis, stablecoins accounted for 84% of illicit on-chain transaction volume in 2025, making them the most commonly used digital asset in criminal activity. Investments will be permitted only through the country’s five largest regulated exchanges: Upbit, Bithumb, Korbit, INEX, and Coinone. However, anti-money-laundering experts warn that criminal groups are increasingly shifting toward casinos and chip-to-cash cycles, which they consider safer than crypto. The warning follows reports that Chinese nationals used casinos on Jeju Island and in other regions to launder money obtained from voice-phishing scams.
