The U.S. Attorney’s Office for the Western District of Washington secured $400 million in asset forfeiture as part of a guilty plea from two Estonian nationals who operated a $577 million crypto Ponzi scheme.
Sergei Potapenko and Ivan Turõgin, both 40, pleaded guilty to conspiracy to commit wire fraud after selling fraudulent crypto mining contracts through their company HashFlare.
However, the defendants lacked the necessary computing power to conduct the crypto mining they promised, instead using falsified data on their platform to create the illusion of success.
As part of their agreement, the defendants agreed to forfeit assets, including real estate, luxury vehicles, and crypto accounts, according to a statement on Thursday.

Same Judge Who Ruled in Favor of Ripple Hands Down Sentence in $8.4 Million Crypto Ponzi
The judge who rattled the crypto industry with her game-changing XRP ruling is making headlines again. Judge Analisa Torres, whose landmark decision that retail XRP sales weren't securities, sentenced a crypto Ponzi scheme promoter to 30 months in prison Thursday for defrauding investors of $8.4 million. The sentence comes just days after the SEC filed an appeal brief challenging Torres' earlier ruling that distinguished between institutional and retail sales of XRP, establishing how certain tok...
"Between 2015 and 2019, HashFlare’s sales totaled more than $577 million, but HashFlare did not possess the requisite computing capacity to perform the vast majority of the mining," said the U.S. Attorney’s Office.
Potapenko and Turõgin now face up to 20 years in prison for conspiracy to commit wire fraud, with their sentencing scheduled for May 8.
The two of them also admitted to running another fraudulent operation, Polybius, an Initial Coin Offering (ICO) for a digital bank project that raised approximately $31 million in 2017.
The funds raised through Polybius were never invested in the bank, and no dividends were ever paid to investors, further adding to the fraudulent nature of their schemes, the statement reads.
"Instead of using the proceeds to create a digital bank, Turõgin and Potapenko used a large portion of the proceeds for their own personal benefit," the FBI Seattle office said.

Austrian Police Uncover $1.2 Million 'Rip-Deal 2.0' Crypto Fraud
Detectives in Vienna, Austria have disrupted a $1.26 million (€1.2 million) crypto fraud operation they’re calling “Rip-Deal 2.0.” A 39-year-old suspect with a long series of past convictions was arrested in Milan, Italy, earlier this year with help from Europol, according to English-language local news outlet The International. In October, a regional court sentenced the person to three years in prison. The suspect reportedly engaged in a new variation of the Rip-Deal scam, which traditionally u...
The U.S. Attorney’s Office alleges the defendants laundered the fraud proceeds through at least 75 properties, six luxury vehicles, crypto wallets, and thousands of crypto mining machines.
The FBI’s Seattle Field Office played a key role in the investigation, working with international law enforcement agencies to ensure the defendants were apprehended and extradited from Estonia.
Both culprits were arrested on November 20, 2022, in Tallinn, Estonia, and were later extradited to the U.S. to face charges.
The FBI also calls for additional individuals who believe they were victims of the Hashflare fraudulent scheme to come forward. It has set up a dedicated website where potential victims can submit information.

86-Year-Old Former Lawyer to Pay $14 Million for Running Bitcoin Ponzi Scheme
An 86-year-old former California attorney, David Kagel, has been sentenced to five years of probation and ordered to pay nearly $14 million after admitting to conducting a multimillion-dollar Bitcoin Ponzi scheme.

The guilty plea and the forfeiture are part of a broad effort by U.S. authorities to hold crypto operators accountable for fraudulent activities.
The crackdown follows significant actions taken earlier in 2024 when the U.S. Attorney’s Office for the Western District of Washington secured a record-breaking $1.51 billion in fines.
The majority came from the global crypto exchange Binance, which was penalized in a $4.3 billion settlement for violating U.S. regulations.
