OneCoin: The $4 Billion Crypto That Never Existed

On 25 October 2017 Ruja Ignatova, the Bulgarian founder of OneCoin, boarded a Ryanair flight from Sofia to Athens. Nobody has been able to say for certain where she went next. Nine years later the FBI still lists her among its Ten Most Wanted fugitives, the US State Department offers up to $5 million for information leading to her arrest, and prosecutors in Germany have charged her too. The coin she sold to the world, which US prosecutors say raised more than $4 billion, never existed in any form a computer scientist would recognise.

OneCoin ran from 2014 to 2019 out of Sofia. At its height it claimed more than 3 million members worldwide. Ignatova, a lawyer with a doctorate who called herself the "Cryptoqueen", filled arenas, including Wembley Arena in London in June 2016, and told crowds OneCoin would overtake Bitcoin. What they were buying, according to every court that has looked at it, was a number in a database the company controlled.

What people actually bought

Bitcoin works because its record of who owns what, the blockchain, is a public ledger copied across thousands of computers, so no single company can change it. Anyone can check it. OneCoin claimed to have one. It did not. As DL News summed up the court record, OneCoin "had no blockchain" and relied on industry jargon to lure investors. The balances customers saw were entries on servers run by the company, which could set them however it liked.

The product was sold in bundles. Members bought "educational packages", courses on crypto trading and investing, that came with tokens which could be turned into OneCoins. The packages ranged from a few hundred euros to tens of thousands. Members earned commissions for recruiting others, who recruited others in turn: a pyramid, run through a multi-level marketing network across Europe, Asia, Africa and Latin America.

The price only ever went up, because OneCoin set it. There was no open market where a member could sell OneCoins for cash at that price. It was like being shown a share price on a screen by a broker who also refuses to let anyone sell. The company kept promising that a public exchange listing was coming. It never came.

The money and the launderers

The money was real even if the coin was not. Investors paid billions into bank accounts and front companies, and US prosecutors traced a large part of it through a web of launderers and lawyers.

Mark Scott, an American lawyer and former partner at the firm Locke Lord, was convicted in New York in November 2019 of conspiracy to commit money laundering and bank fraud for moving about $400 million of OneCoin proceeds through fake investment funds. He was sentenced to 10 years in January 2024. Karl Sebastian Greenwood, the Swedish co-founder who ran OneCoin's sales network, pleaded guilty and on 12 September 2023 was sentenced to 20 years and ordered to pay $300 million. Both later lost their appeals at the US Court of Appeals for the Second Circuit. Irina Dilkinska, OneCoin's head of legal and compliance, pleaded guilty and was sentenced to four years on 3 April 2024 and ordered to forfeit $111.4 million.

Ignatova's younger brother, Konstantin Ignatov, took over the company after she disappeared. He was arrested at Los Angeles International Airport in March 2019, pleaded guilty and testified for the prosecution. On 5 March 2024 Judge Edgardo Ramos sentenced him to time served, the 34 months he had already spent in jail, even though prosecutors acknowledged he had lied on the stand in Scott's trial.

The missing founder

Ignatova had good reason to run. US prosecutors had filed a sealed criminal complaint against her in October 2017, the same month she flew to Athens, and later indicted her for wire fraud, money laundering and securities fraud. The FBI added her to its Ten Most Wanted list in June 2022 with a $100,000 reward. The State Department raised that to up to $5 million on 26 June 2024.

What happened to her is contested. A BBC investigation in 2024, citing police informants, reported that a Bulgarian crime figure may have ordered her killing in 2018. A documentary for the German broadcaster WDR, by the filmmaker Johan von Mirbach, reported that she is alive and living in Cape Town, South Africa, and noted that Düsseldorf police say the man named as her alleged killer was in a Dutch prison at the time. A Bulgarian police official said in a podcast interview that he believes she is alive. None of these accounts has been confirmed by any authority, and no body has been found.

Getting the money back, slowly

Nine years after Ignatova vanished, victims are only beginning to see money. On 13 April 2026 the US Justice Department opened a remission process, a claims procedure that lets victims apply for a share of forfeited criminal assets, for anyone who bought OneCoin between 2014 and 2019. More than $40 million was available, run by the administrator Kroll, with a deadline of 30 June 2026. Jonathan Levy, a lawyer for victims, warned DL News that many small investors would struggle to produce years-old paperwork in time.

Europe has moved on Ignatova's property. On 16 January 2026 the Royal Court of Guernsey registered a German confiscation order over £8.59 million of her funds, to be returned to Germany for victims. In September 2025 prosecutors in Bielefeld, Germany, indicted her to stop the statute of limitations running out, naming about 17,500 victims and €57 million of losses from December 2015 to August 2016 alone, paid into accounts of a company called IMS in the town of Greven. In October 2026 they said they had recovered €10.1 million from the sale of two of her London flats. Under German law the charges against her remain live until the summer of 2031.

Set against more than $4 billion, the sums coming back are small. Ignatova has not been convicted of anything, and on the charges against her she is presumed innocent until a court rules.
