Ruja Ignatova, commonly known as the "Cryptoqueen," has now been added to the FBI's list of ten most wanted people.
In a press release issued on Thursday, the FBI said that it would pay up to $100,000 in exchange for information that would result in Ignatova's capture.
In 2014, Ignatova allegedly created the $4 billion cryptocurrency Ponzi scheme known as OneCoin.
Ignatova promoted OneCoin as a "Bitcoin killer" while traveling the globe and speaking at conferences, however it was later discovered by investigators that OneCoin was not based on any blockchain technology.
In 2017, the US issued a federal arrest warrant for Ignatova.
That same year, Ignatova disappeared. In October 2017, Ignatova, according to a press release from the FBI, traveled from Sofia, Bulgaria, to Athens, Greece.
