Vlad-Călin Nistor built CoinFlux into one of Romania’s better-known cryptocurrency exchanges, but the business ultimately became entangled in an international fraud case that prosecutors said used Bitcoin to move the proceeds of fake online sales back to Romania. Nistor, who was 33 when the U.S. Justice Department announced his guilty plea in 2020, pleaded guilty to a federal RICO( Racketeer Influenced and Corrupt Organizations Act)–conspiracy charge and was later sentenced to 40 months in prison. He was ordered to pay $91,200 in restitution, a $100 special assessment and forfeit property covered by an agreed forfeiture order.
Nistor is also referred to publicly as Vlad Nistor and, in Romanian records and reporting, as Nistor Vlad-Călin. No credible source reviewed for this investigation established a separate criminal alias. He is a Romanian national from Cluj-Napoca and founded CoinFlux Services SRL in 2015. The company became a cryptocurrency exchange dealing in Bitcoin and other digital assets, with Nistor serving as its chief executive and owner. Contemporary reporting described CoinFlux as a significant player in Romania’s crypto market. The company has said it processed more than €220 million in transactions and served more than 27,000 customers between 2015 and 2018.
The criminal case was considerably more serious than a dispute over a cryptocurrency exchange. U.S. prosecutors described a transnational organization operating primarily from Alexandria, Romania, that advertised nonexistent cars and other expensive goods on eBay, Craigslist, Amazon and other online marketplaces. Victims were persuaded to send money through wire transfers, money orders, prepaid cards and other payment methods. The conspirators used fabricated identities, fake invoices and even impersonated eBay customer-service representatives and military personnel to make the transactions appear legitimate. The money was then converted into cryptocurrency and moved overseas, where exchangers converted it back into fiat currency.
That operation became known to investigators as the Alexandria Online Auction Fraud Network. A 2018 federal indictment charged 15 foreign nationals with offenses including RICO conspiracy, wire-fraud conspiracy, money-laundering conspiracy and aggravated identity theft. Additional defendants were charged in a later indictment, bringing the number of people charged across the case to 20. The Justice Department said the operation victimized thousands of Americans. Later federal appellate litigation concerning another participant put the losses attributable to the online-auction scheme at at least $2.7 million.
Nistor’s role was not described by prosecutors as that of the person creating the fake advertisements. His importance to the scheme was the movement of cryptocurrency. According to the Justice Department, he founded and owned CoinFlux Services SRL and exchanged cryptocurrency into local fiat currency for Romanian members of the criminal enterprise, knowing that the Bitcoin represented proceeds of illegal activity. Prosecutors specifically cited more than $1.8 million in Bitcoin that Nistor exchanged for co-defendant Bogdan-Stefan Popescu.
Popescu was described by prosecutors as a key organizer. According to his plea documents, he operated a car wash in Bucharest and helped coordinate the network, including the acquisition of fraudulent advertising materials and tools for concealing the conspirators’ locations. Prosecutors said he transferred Bitcoin obtained from fraudulent schemes to people including Nistor, who converted it into fiat currency. The resulting funds were then deposited into accounts associated with employees and family members.
Another significant figure was Beniamin-Filip Ologeanu, who pleaded guilty to the same RICO-conspiracy offense. Court documents said Ologeanu and others posted fraudulent advertisements and arranged for proceeds to be converted into other forms of payment and Bitcoin. Bulgarian exchange operator Rossen Iossifov was separately prosecuted after prosecutors alleged that his business, RG Coins, was another cryptocurrency conversion point in the network. Unlike Nistor, Iossifov went to trial, was convicted of RICO and money-laundering conspiracy, and received a 10-year sentence with more than $2.6 million in restitution.
The case against Nistor began publicly surfacing in Romania in December 2018. Romanian authorities, working with U.S. investigators, searched properties associated with him and CoinFlux. Reports at the time said investigators seized computers, hard drives and USB devices. Nistor was arrested on a U.S. warrant alleging fraud, computer fraud, organized-crime involvement and money laundering. A Romanian court initially placed him under judicial supervision, but the decision was later overturned and he was detained pending extradition.
Nistor was extradited to the United States on January 31, 2019. At that stage, his Romanian lawyer maintained that Nistor had no way of knowing that the Bitcoin passing through CoinFlux came from criminal activity. Nistor ultimately took a different legal position in the United States. On May 19, 2020, he pleaded guilty to one count of conspiracy to commit a RICO offense. A federal judge accepted the plea and adjudicated him guilty.
The final judgment, entered in September 2021, sentenced Nistor to 40 months in federal prison. It ordered $91,200 in restitution and imposed a $100 assessment; the fine was waived. The judgment also required forfeiture of Nistor’s interest in property identified in an agreed forfeiture order. The court did not impose a period of supervised release.
CoinFlux itself did not survive the episode as an operating exchange. The company’s current website says the platform stopped operating in 2024, that customer fiat funds were refunded and that user data was subsequently erased. Romanian company records reported by a business-information service indicate that CoinFlux Services SRL was ultimately removed from the register in March 2026. Its reported 2024 revenue was only 2,164 Romanian lei, compared with more than 15.1 million lei in 2017.
There is an important distinction between the criminal case against Nistor and the wider history of CoinFlux. A handful of online customer complaints existed before his arrest, including an unverified 2018 Trustpilot post accusing the company of withholding funds. Such reviews are not evidence of criminal conduct and should not be confused with the federal case, which concerned Nistor’s dealings with members of the fraud network. No separate regulatory enforcement action against Nistor for consumer fraud was identified in the credible sources reviewed.
Nistor’s personal circumstances after prison are less clear. Publicly available sources reviewed for this investigation do not establish a verified current residence or a reliable present-day business profile. A November 2025 letter from the law firm Chaplin, Bénédicte & Co., sent on Nistor’s behalf to OffshoreAlert, stated that he had completed his sentence, been rehabilitated and was then engaged in legitimate business activity, specifically investing in startups. The letter sought removal of an OffshoreAlert article about the case under GDPR’s right-to-erasure provisions.
The letter is significant because it shows that the consequences of the conviction have not ended simply because the prison sentence did. Nistor’s representatives argued that continued publication of historical reporting was disproportionately damaging his professional rehabilitation and asked OffshoreAlert to remove the article and associated copies or archives. They also reserved the right to pursue a complaint with the relevant data-protection authority if the request was rejected.
The broader lesson is not that cryptocurrency itself created the fraud. The case demonstrates something more specific: a legitimate-looking financial technology business can become part of an illicit money trail when criminal proceeds are converted, moved and cashed out through digital-asset infrastructure. Nistor was not convicted of personally running the fake eBay advertisements or stealing money directly from individual buyers. He pleaded guilty to participating in a RICO conspiracy after prosecutors established that CoinFlux was used to exchange more than $1.8 million in Bitcoin that he knew represented criminal proceeds.
That distinction matters. So does the final judgment. The allegations became a conviction, the conviction produced a 40-month sentence and restitution, and the exchange at the center of the case ultimately disappeared.
What remains unresolved is not Nistor’s criminal responsibility, which was settled by his guilty plea and judgment, but what came afterward. His lawyers now portray him as a rehabilitated entrepreneur and startup investor, while the public record still largely defines him through the CoinFlux case. Whether his post-prison business career succeeds will depend in part on whether investors and counterparties judge rehabilitation by the passage of time or by the documented history of the business he once controlled.
For the cryptocurrency industry, the case remains a reminder that sophisticated technology does not eliminate an old problem. When money moves rapidly across borders, the people standing between fraud and cash-out can become just as important to a criminal investigation as the people who stole the money in the first place.
