Konstantin Ignatov released from prison after serving his sentence in the OneCoin case

The OneCoin scam system, which defrauded millions of investors worldwide, continues to make headlines in courtrooms. After pleading guilty to its role in this $4 billion cryptocurrency fraud, Konstantin Ignatov was released from U.S. custody on March 5, 2026. This release comes after he served his full sentence, marking a significant step in dismantling what remains one of the largest crypto scams in history.

Three and a Half Years of Detention for Conspiracy in the Fraudulent Scheme

U.S. Judge Edgardo Ramos sentenced Konstantin Ignatov to 34 months in prison, a sentence recommended by prosecutors with whom the fraudster cooperated. His release calculation accounts for the time he already spent in pretrial detention before pleading guilty. In addition to imprisonment, the court also imposed two years of supervised release and ordered the confiscation of $118,000. These measures reflect the severity of the charges against Ignatov, who helped his older sister orchestrate the scheme from its inception.

Konstantin Ignatov’s Key Role in the Expansion of OneCoin

Ruja Ignatova recruited her brother as a personal assistant during the OneCoin boom, spanning from Q4 2014 to Q3 2016. After his sister disappeared in 2017, Konstantin Ignatov gradually established himself as the de facto leader of the program. Prosecutors documented how he continued the fraudulent activities, maintained the system, and perpetuated the scam. During the trial, Ignatov admitted to lying under oath about the supposed destruction of his laptop in Las Vegas, a revelation that raised questions about the reliability of other testimonies in the case.

Ignatov’s Co-Conspirators Facing Severe Sentences

Beyond Konstantin Ignatov’s case, several major players in the OneCoin scheme received substantial sentences. Mark Scott, a former lawyer who laundered $400 million through the scheme, was sentenced to 10 years in January 2025, with an order to pay restitution of $392 million. Karl Sebastian Greenwood, co-founder of OneCoin and close associate of Ignatova, received a 20-year prison sentence in September 2025. Greenwood embezzled approximately $300 million from OneCoin, spending it on luxury travel, high-end clothing, and prestigious properties. Irina Dilkinska, head of legal and compliance at OneCoin, also pleaded guilty in November 2025 and faces a maximum sentence of 10 years.

Konstantin Ignatov’s Sister Remains at Large Despite FBI Efforts

While Konstantin Ignatov has regained his freedom, his sister Ruja Ignatova has been on the run since 2017. Although she is among the FBI’s ten most wanted fugitives, her whereabouts remain unknown. Rumors—never confirmed—suggest that a local drug lord may have eliminated her in 2018. Ignatova’s absence complicates investigation efforts and leaves many questions unanswered about the true extent of her involvement in the OneCoin criminal network.
