An interesting story from the world of crypto scams that shows how dangerous this segment can be. Ruja Ignatova is a name that has become synonymous with one of the biggest financial frauds in history. It’s about OneCoin, which was introduced in 2014 as supposedly a strong competitor to Bitcoin.

The woman of Bulgarian-German descent was born in 1980 in the city of Ruse and moved to Germany as a child. According to her, she held a PhD in international law and even worked at McKinsey. But instead of staying in legal business, Ruja Ignatova decided to launch her own cryptocurrency.

Appealing promises were her main weapon. She lured investors from over 100 countries with astronomical profits, claiming that OneCoin was supported by blockchain technology. In reality, it was a typical Ponzi scheme. The scale was impressive — about $4 billion, and some estimates put losses at up to £12.9 billion.

In 2016, Ruja Ignatova made a provocative statement: that in two years, no one would be talking about Bitcoin. The forecast did not come true, but her days as an active scammer were numbered. In October 2017, she disappeared on a flight from Sofia to Athens, leaving behind a exposed company and her brother, who later confessed to crimes.

Today, Ruja Ignatova is on the FBI’s list of the 10 most wanted criminals. A reward of $5 million has been offered for her head, although Europol suggested a modest amount — £4,100. It is believed she moves with fake passports and may have undergone plastic surgery. There is even a version that she was eliminated by the Bulgarian mafia.

Finding her is almost impossible thanks to a powerful network of protectors. There are suspicions that influential people in Bulgaria helped her hide from law enforcement. The last confirmed trace was at Athens airport. No recent photos are available. There are assumptions that she is hiding in Russia or Greece, possibly under armed guard.

Paradoxically, OneCoin continues to operate in some African and Latin American countries, attracting new victims. The story of this scam has inspired a number of documentary projects and media investigations, including the well-known BBC podcast "The Missing Crypto Queen."

The case of Ruja Ignatova is a classic example of how academic intelligence can be combined with criminal audacity. It’s a great lesson for everyone considering investing in crypto projects: always check if the project is registered, whether it has real technology, and a good reputation. Unregistered enterprises promising fantastic returns are almost a guaranteed way to lose money.
