Recently, I’ve been looking into some historical cases in cryptocurrency, and I have to mention the name Ружа Игнатова. This Bulgarian-German woman scammer created OneCoin, which was later exposed as one of the biggest Ponzi schemes in history. Her story is still being discussed today, and I think it’s worth a deep dive.

Ружа Игнатова was born on May 30, 1980, grew up in Ruse, Bulgaria, and moved to Germany with her family at age 10. She appears to be an elite: she earned a Ph.D. in International Law from the University of Constance and claimed to have worked at McKinsey. But these glamorous backgrounds were actually just stepping stones for her later big scam.

In 2014, Ружа Игнатова launched OneCoin, packaging it as a strong competitor to Bitcoin. This woman was very clever; she promised investors astronomical profits, claiming that this currency was supported by blockchain technology. But in reality? It was all fake. The scheme attracted investors from over 100 countries, ultimately raising $4 billion, with some estimates even saying losses reached as high as £12.9 billion.

By 2016, Ружа Игнатова was still very arrogant, publicly claiming that in two years no one would be talking about Bitcoin anymore. But instead, she became one of the most notorious figures in crypto history. In October 2017, she disappeared after a flight from Sofia to Athens, leaving behind a collapsed scam and a brother who confessed.

Since then, the FBI listed her on the top ten most wanted in 2022, offering a $5 million reward. Europol was also pursuing her, although they only offered a £4,100 bounty, which was later criticized as too low. Some speculate she might have used a fake passport, undergone plastic surgery, or been murdered by the Bulgarian mafia. The last confirmed sighting was at Athens airport, after which there was no physical evidence.

Interestingly, Ружа Игнатова’s escape tactics suggest she might be hiding in places like Russia or Greece, possibly accompanied by armed bodyguards. There also seems to be a powerful network behind her—some suspect that influential figures in Bulgaria helped her evade law enforcement before her disappearance.

What’s more shocking is that even after the scheme was fully exposed, OneCoin continued operating in some African and Latin American countries, continuing to harm victims. Ружа Игнатова’s story even inspired TV shows and in-depth investigations, like the BBC podcast “The Missing Crypto Queen.”

What does this case tell us? While the crypto market is full of opportunities, it’s also full of traps. Ружа Игнатова used her academic background and carefully woven lies to scam billions of dollars, reminding us to be especially cautious when investing in unregistered projects. History repeats itself—where there are greedy investors and clever scammers, similar tragedies can happen again.
