An Ohio investment manager has been sentenced to nine years in federal prison for operating a $10 million cryptocurrency Ponzi scheme that promised guaranteed Bitcoin returns to investors. Rathnakishore Giri used the classic fraudulent structure of paying earlier investors with funds from new participants. The supporting evidence appears in the filing.
According to the U.S. Department of Justice, Giri collected money from investors by promising regular and guaranteed profits through Bitcoin derivative trading operations.
The sentence was announced on May 19, 2026, with authorities confirming the scheme was structured around Bitcoin derivative transactions.
The case highlighted how money collected through cryptocurrency investment promises can quickly transform into criminal proceeds. According to prosecutors, Giri used funds from new investors to make payments to previous participants, operating the system like a classic Ponzi structure.
Court Sentence Announced Through Official Statement
According to a statement published by the U.S. Department of Justice, Giri collected money by promising investors regular and guaranteed earnings. The official announcement can be accessed here.
Authorities stated that the scheme was presented as a professional trading strategy involving Bitcoin and derivative products, but in reality was dependent on new money inflows. When this structure collapsed, losses also spread to investors who entered the system in the early stages.
Bitcoin Frauds Increase Industry Pressure
The FBI has been tracking this area as a risk category for a long time, saying that cryptocurrency and artificial intelligence-based frauds have cost Americans billions of dollars. The agency’s recent warnings show that digital assets are still being used intensively for fake return promises.
This case once again reminded that investors need to be careful against “guaranteed profit” rhetoric in particular. The difference between legitimate trading strategies and Ponzi schemes in the crypto market often cannot be understood without examining official records and fund flows.
Prominent Accusation Structure in the Case
The prosecution reported that Giri convinced investors that money was being made through Bitcoin derivative transactions and that the collected funds were not used as promised. The scheme required constant new investment inflows to be able to make payments to early participants.
The 9-year sentence given by the U.S. federal court became one of the recent examples showing that prison sanctions in crypto-related investment frauds can be aggravated.
Authorities emphasize that in similar cases, investors should specifically request verifiable documents regarding registration, auditing and fund usage.
