The US government has upped the reward for information leading to the arrest of OneCoin co-founder, Ruja Ignatova, to $5 million. Known as Cryptoqueen, Ignatova is wanted for one of the largest transnational fraud schemes in history, defrauding investors of over $4 billion through the OneCoin Ponzi scheme. The increased reward, a significant jump from the previous $250,000, has fueled speculation about Ignatova's rumored death in 2018.

Ignatova, a Bulgarian-born German citizen, has been on the run since 2017, evading charges of fraud and money laundering from US and German authorities. Rumors suggest she may have altered her appearance and could be moving with armed security. There are also unconfirmed reports of her death at the hands of a Bulgarian drug lord. However, these could be tactics to mislead authorities. The search for Cryptoqueen continues, with the US government's increased reward indicating their determination to bring her to justice.
