In this lesson
- find out how OneCoin sold a "cryptocurrency" that did not exist
- understand how MLM networks and "educational packages" spread it around the world
- learn where Ruja Ignatova may be and which warning signs anyone could check
What was OneCoin? OneCoin was a fake cryptocurrency launched in 2014 by Ruja Ignatova, the self-styled "Cryptoqueen", and Sebastian Greenwood. It had no real blockchain – its "price" was simply set by the company. According to US prosecutors, millions of people around the world put in more than 4 billion dollars. Ignatova vanished in October 2017 and as of October 2026 she is still on the FBI's Ten Most Wanted list; co-founder Greenwood is serving 20 years in prison.
A cryptocurrency without a blockchain is like a restaurant without a kitchen. OneCoin did not let that stop it – it simply sold the menu, the cookbooks and the dream of opening your own branch.
How OneCoin worked#
- You bought an "educational package". OneCoin officially sold trading courses – from about 100 euros for a starter package up to over 100,000 euros for the biggest ones.
- Each package came with "tokens" that could supposedly be used to "mine" OneCoins. The more you paid, the more coins you would get.
- You watched your balance grow. In your account you saw OneCoins and a price that only went up. The company set that price itself.
- You recruited others. Commissions for bringing in new buyers, and for the people they brought in, made OneCoin an MLM machine with sellers in dozens of countries.
- You could not really cash out. The internal exchange limited sales, and the promised public listing never came.
Unlike Bitcoin, there was no public blockchain where anyone could check the coins and transactions. According to prosecutors, OneCoins were worthless and the "mining" was fiction. Money flowed in from new members – a Ponzi scheme dressed up as a cryptocurrency.

Where is Ruja Ignatova?#
Nobody knows for sure. Ignatova was due to speak at a OneCoin event in Lisbon in October 2017 – instead she flew to Athens and has not been seen since. She had reportedly learned that US authorities were investigating her. Her story became widely known through the BBC podcast "The Missing Cryptoqueen".
- The official position: as of October 2026 the FBI still lists her among its Ten Most Wanted Fugitives and US authorities offer a reward of up to 5 million dollars. She is charged with fraud and money laundering in the US and is presumed innocent until a court rules.
- Reported claims: in 2023 Bulgarian investigative journalists published a police document claiming she was killed in 2018. No authority has confirmed this, and the FBI works on the assumption that she is alive.
- The money: authorities keep finding pieces of it. German prosecutors seized about 10 million euros from the sale of her London flats, and in January 2026 a court in Guernsey forfeited about 8.6 million pounds – money meant to help victims.
What happened to the others?#
- Sebastian Greenwood, co-founder and top seller, was arrested in Thailand in 2018, pleaded guilty in the US in December 2022 and was sentenced to 20 years in September 2023. According to the DOJ he received more than 300 million dollars from the scheme.
- Konstantin Ignatov, Ruja's brother, who ran OneCoin after she vanished, pleaded guilty, testified for the prosecution and, as a cooperating witness, got a much milder sentence than the others.
- Mark Scott, a US lawyer, was convicted of laundering about 400 million dollars of OneCoin money and sentenced to 10 years in January 2024.
Warning signs you could have seen#
- No public blockchain. A real cryptocurrency lets anyone check every transaction. OneCoin had nothing to check.
- The company sets the price. A coin whose price only goes up and is decided by its issuer is not a market.
- You cannot sell. If you can buy freely but withdrawals are limited, you own a number on a screen.
- "Education" as the product. Expensive courses with coins as a "bonus" are a way around regulations.
- Commissions for recruiting. The money moved through sellers who earned on every new member.
- Glamour instead of technology. Ball gowns, arenas and magazine covers – but no developers you could talk to and no open code.
If you cannot check it, do not buy it
Before you buy any cryptocurrency, find it on a public block explorer and on well-known independent exchanges where you can actually sell it. Be very careful with anything sold through personal networks, seminars and commissions – friends and family often recruit in good faith because they were fooled too. And if someone offers to "recover" your lost OneCoin money for a fee, it is another scam.
Common myths#
- "OneCoin was a failed crypto project." It was not a crypto project at all. There was nothing to fail – only a database with numbers.
- "Only naive people fell for it." Victims included educated people, business owners and whole communities. The sellers were often their friends.
- "It is over." Parts of the OneCoin network kept recruiting long after 2017, and copies of the same model keep appearing under new names.
Summary
- OneCoin (2014–2017) was sold as a cryptocurrency but had no real blockchain; the company set its price.
- It spread through an MLM network selling "educational packages"; according to prosecutors it took in over 4 billion dollars.
- Ruja Ignatova vanished in October 2017 and as of October 2026 is still on the FBI's Ten Most Wanted list.
- Sebastian Greenwood got 20 years, Mark Scott 10 years; Konstantin Ignatov, who cooperated, far less.
- Warning signs: nothing to check on a blockchain, a price set by the issuer, no way to sell and big recruiting commissions.
