Ohio manager gets 9 years for $10M crypto Ponzi scheme. FBI data shows $11.36B lost to crypto scams in 2025. Key red flags for traders.
An Ohio investment manager will spend nine years in federal prison after running a $10 million cryptocurrency Ponzi scheme. Rathnakishore Giri, 31, of New Albany, received the sentence on Monday alongside three years of supervised release. Federal prosecutors said Giri marketed himself as a skilled crypto and Bitcoin (BTC) derivatives trader, promising investors guaranteed profits with "zero risk" while assuring them their principal was safe. In reality, he used new investor funds to pay earlier clients – a textbook Ponzi structure.
The U.S. Department of Justice revealed that Giri suffered major trading losses and never generated the returns he advertised. When investors tried to withdraw, he gave misleading excuses and delayed payments to hide the collapse. Giri was first charged in November 2022 with five counts of wire fraud and pleaded guilty to one count in October 2024. Prosecutors also disclosed that he continued soliciting funds even while awaiting sentencing, an additional misconduct reflected in an amended plea agreement.
What this means: A promise of "zero risk" or protected principal in crypto is a near-certain red flag. Real trading profits come with volatility and loss exposure.
The Justice Department's Fraud Section handled the prosecution, led by Acting Deputy Chief Lucy B. Jennings and Trial Attorney Tamara Livshiz.
The Giri sentencing fits into a troubling national pattern. FBI data showed Americans lost approximately $11.36 billion to crypto scams in 2025, a 22% increase from the prior year. The scheme represents only 0.09% of that total, yet its structure mirrors hundreds of other unregistered crypto investment offerings that regulators are still chasing.
For traders, the key question is not whether fraud exists – it clearly does – but how to distinguish legitimate opportunities from Ponzi-like structures without getting caught in the hype of guaranteed returns. The Giri case offers a concrete template for due diligence.
Several warning signs emerged that investors can use as a checklist:
For anyone evaluating a crypto investment manager, the Giri case provides a practical framework. The first filter is the source of returns: can the manager explain, in plain terms, how profits are generated? If the answer includes complex jargon but no clear mechanism, treat it as a red flag.
The second filter is custody and transparency. Legitimate managers typically use regulated exchanges or custodians and provide real-time statements. In the Giri scheme, investors had no visibility into actual trade execution.
The third filter is the withdrawal process. Any pattern of delays, excuses, or partial payments should trigger immediate scrutiny.
Based on patterns from the Giri case and similar prosecutions, consider these flags when reviewing any crypto investment offer:
Practical rule: If it sounds too good to be true, it probably is. The Giri sentence is a reminder that even sophisticated-sounding crypto traders can be hiding fraud.
Regulators have been ramping up enforcement. The CFTC and SEC have brought multiple actions against crypto Ponzi operators, and the recent appointment of DJ Hennes to the CFTC signals further crackdowns on crypto derivatives risk. Yet fraud continues because the incentive structure is powerful: easy money from trusting investors, aided by the perception that crypto is unregulated and anonymous. The FBI data showing $11.36B in losses confirms that enforcement alone cannot stop every scheme.
That said, the sentencing also demonstrates that enforcement is improving. The Justice Department's ability to trace crypto flows and build cases against operators like Giri is a positive signal for market integrity.
For traders, the best defense remains personal due diligence. Do not rely on promises; demand proof of trading activity, audited statements, and a clear withdrawal process. The Giri case shows that even as regulators catch up, the burden rests on individual investors to avoid the trap.

Until then, every promise of guaranteed crypto returns should be met with skepticism – and a quick check against the FBI's fraud data.
