Ohio Investment Manager Sentenced To Nine Years In $10M Crypto Ponzi Case

An Ohio investment manager has been sentenced to nine years in prison for running a cryptocurrency investment fraud that raised more than $10 million from investors, many of them in and around Columbus. Rathnakishore Giri, 31, of New Albany, Ohio, also received three years of supervised release after pleading guilty to wire fraud.

The case centered on Giri’s pitch that he was an expert crypto trader with a specialty in Bitcoin derivatives. Prosecutors said he promised investors lucrative returns with no risk to their principal and guaranteed that their original investment would be returned. Instead, he often used money from new investors to repay earlier investors, the classic structure of a Ponzi scheme.

The fraud also relied on delay tactics once investors tried to withdraw. Giri had a record of failed investments and repeatedly misled customers about why cashouts or principal repayments were not happening. The promises were built around trust, trading expertise and guaranteed downside protection, the same combination that has appeared across many crypto investment-fraud cases where victims believe they are joining a managed strategy rather than sending money into a collapsing scheme.

Guilty Plea Did Not Stop New Solicitation

The most damaging detail in the sentencing record is what happened after the guilty plea. Giri pleaded guilty to one count of wire fraud in October 2024, but while on pretrial release and waiting for sentencing, he continued soliciting money from crypto investors. Prosecutors said that conduct caused additional harm to new victims, and Giri later admitted to the extra activity under an amended plea agreement.

That puts the case beyond a simple failed-trader story. The court record describes a manager who kept presenting himself as a crypto investment expert even after the criminal case had already advanced. For victims, the risk was not only market volatility or a bad Bitcoin derivatives strategy. It was the false promise that principal was safe while investor funds were being recycled, delayed or lost.

The FBI investigated the case, and the Justice Department’s Fraud Section prosecuted it. The DOJ also directed victims of cryptocurrency investment fraud to the FBI’s Internet Crime Complaint Center, which has become one of the main reporting channels for online investment scams, fake trading platforms and crypto fraud complaints.

Guaranteed Returns Remain The Core Warning Sign

The Giri case reinforces one of the oldest red flags in crypto fraud: guaranteed returns with no principal risk. Bitcoin derivatives can be volatile even for experienced traders, and no legitimate manager can remove market risk while promising high returns. When a crypto investment pitch combines “expert trading,” guaranteed principal protection and delayed withdrawals, the risk moves from aggressive strategy to potential fraud.

The warning is especially relevant as crypto investment scams keep adapting around managed accounts, fake platforms, offshore entities and private chat groups. A recent global crypto scam-center crackdown showed how fraud networks continue using investment promises to draw victims into controlled platforms before blocking withdrawals or demanding more money.

Giri’s sentence gives the Ohio case a concrete endpoint: nine years in prison, three years of supervised release and a fraud record tied to more than $10 million raised from investors. The next practical lesson sits with investors before money moves. Any crypto manager promising high returns, guaranteed principal and easy withdrawals should be treated as a custody and fraud risk first, not as a trading opportunity.
