Ruja Ignatova: The Cryptoqueen

On 25 October 2017, Ruja Ignatova boarded a Ryanair flight from Sofia to Athens. She has not been reliably seen since. She was 37, a Bulgarian-born German with a law doctorate and a past at McKinsey, and the face of OneCoin, a digital currency that she had sold to millions of people as the coin that would kill bitcoin. Two weeks before she flew, a federal court in New York had quietly filed charges against her.

Nine years later she is one of the most wanted people on earth. The FBI put her on its Ten Most Wanted Fugitives list in June 2022, and in June 2024 the US State Department raised the reward for information leading to her arrest to up to $5 million. She has never answered the charges. Several of the people around her have been arrested and convicted.

A coin with no blockchain

Ignatova was born in Ruse, Bulgaria, in 1980 and moved to Germany with her family as a child. She earned a doctorate in private international law at the University of Konstanz and worked as a consultant for McKinsey in Sofia. In 2012 a German court gave her a 14-month suspended sentence for fraud linked to her father's purchase of a steel company that soon went bankrupt.

She launched OneCoin in 2014 with Karl Sebastian Greenwood, a Swedish-British network marketer. Members bought educational packages, sets of online trading courses priced from about €100 to more than €100,000, which came with tokens that could supposedly be mined into OneCoins. They earned commissions for recruiting new buyers, and those buyers recruited more. That is the shape of a pyramid scheme: early sellers are paid with later buyers' money, until the new money stops.

Real cryptocurrencies such as bitcoin keep their records on a blockchain, a public ledger copied across thousands of computers so anyone can check every transaction, like a shareholder register that every shareholder can audit. OneCoin had no such thing. Prosecutors said its coins were numbers in a company database, and the price was simply set by OneCoin and only ever went up. There was nowhere outside OneCoin's own website to sell them.

The pitch worked spectacularly. Ignatova filled arenas, including London's Wembley Arena in June 2016, in ball gowns and diamonds, promising that OneCoin would become the world's leading currency. Sellers carried it to Uganda, India, Pakistan, Vietnam, Brazil and across Europe. According to OneCoin's own records, cited by US prosecutors, the scheme took in €4.037 billion in sales between late 2014 and the end of 2016, and booked €2.735 billion in profits.

The disappearance

By 2017 investigators in several countries were closing in. She was secretly charged in New York on 12 October 2017 with wire fraud conspiracy, securities fraud and money laundering conspiracy. Thirteen days later she flew to Athens and dropped out of sight. Her brother, Konstantin Ignatov, took over the company.

Her fate is disputed. In 2023 and 2024, Bulgarian police documents reported by outlets including the BBC and the investigative site Bird.bg claimed that she was killed in 2018 on the orders of Hristoforos Amanatidis, a Bulgarian crime figure known as Taki, who was said to be protecting her. Investigators in Germany doubt it. The state criminal police office in Düsseldorf said the man the documents named as the killer was in custody in the Netherlands at the time, and that it was working on the assumption that she is alive. A German documentary maker, Johan von Mirbach, reported that sources in South Africa had placed her in Cape Town. In May 2023, Krasimir Kamenov, a Bulgarian said to be linked to her, was among four people shot dead in Cape Town. None of the theories has been confirmed.

The people who were caught

Konstantin Ignatov was arrested at Los Angeles International Airport in March 2019. He pleaded guilty to fraud and money laundering charges, cooperated with prosecutors and testified against others. On 5 March 2024 Judge Edgardo Ramos sentenced him to the 34 months he had already served.

Greenwood, arrested in Thailand in 2018 and sent to the United States, pleaded guilty in December 2022. On 12 September 2023 he was sentenced to 20 years in prison and ordered to forfeit $300 million. Mark Scott, a former partner at the law firm Locke Lord, was convicted in November 2019 of laundering about $400 million of OneCoin money through fake investment funds, and was sentenced to ten years in January 2024. Irina Dilkinska, OneCoin's head of legal and compliance, pleaded guilty to wire fraud and money laundering conspiracy.

Following the money

The money has been slower to find than the people. In April 2026 the US Justice Department opened a remission process, a way for victims to claim a share of forfeited assets, offering more than $40 million to people who bought OneCoin between 2014 and 2019 and lost money. The deadline for claims was 30 June 2026.

Europe has moved too. In January 2026 the Royal Court of Guernsey enforced a German confiscation order over about £8.59 million held in Ignatova's name on the island. In September 2025, prosecutors in Bielefeld, Germany, charged her in her absence over alleged offences in 2015 and 2016 involving about 17,500 victims and €57 million in losses, partly to stop the case running out of time. On 5 October 2026 they announced that they had seized about €10.1 million, raised by selling two flats in London's Kensington that they say were bought with OneCoin money, and would use it to compensate victims.

Against the billions that went in, those sums are small. Most OneCoin buyers have recovered nothing, and the woman who sold them the dream remains, officially, missing.
