Ronald Spektor, a 23-year-old Brooklyn resident, has been sentenced to prison for his role in a cryptocurrency theft scheme that prosecutors said targeted about 100 Coinbase users and resulted in nearly $15.944 million in losses.
Spektor, who lives in Sheepshead Bay, was sentenced on September 23, 2026, by Brooklyn Supreme Court Justice Danny Chun to four to 12 years behind bars. He pleaded guilty on September 2 to all 31 charges included in the indictment.
The case was investigated by the Brooklyn District Attorney’s Office for about a year and centered on a phishing and social engineering operation designed to persuade Coinbase customers to hand over control of their cryptocurrency.
Spektor’s guilty plea covered first-degree grand larceny, first-degree money laundering, first-degree criminal possession of stolen property and related offenses. Prosecutors had requested a seven-to-21-year sentence and opposed the shorter negotiated punishment, according to the Brooklyn District Attorney’s Office.
The final sentence was substantially below the term sought by prosecutors, reflecting the role of plea negotiations in resolving the case.
How the $15.9M Coinbase Scheme Worked
Prosecutors said victims were approached by an individual impersonating a Coinbase representative. The person allegedly claimed that the victim’s account had been compromised by a hacker and instructed them to take steps to protect their cryptocurrency.
Victims then transferred their assets into wallets they believed were secure and controlled only by them. Investigators alleged that Spektor was able to access those wallets and take the cryptocurrency.
The operation depended on social engineering and creating a sense of urgency rather than exploiting a technical weakness in Coinbase’s platform.
Authorities identified approximately 100 victims and interviewed more than 70 during the investigation. Individual losses ranged from tens of thousands of dollars to more than $1 million.
A California victim reportedly lost over $1 million, while a Virginia resident lost more than $900,000. Other reported losses included approximately $53,150 for a Pennsylvania victim and about $38,750 for a Maryland victim.
After the cryptocurrency was stolen, investigators said the funds were moved through swapping and mixing services, gambling websites and online stores before being converted. Authorities described the transactions as part of a broader laundering process used to obscure the movement of stolen digital assets.
Blockchain records, transaction data, digital forensic evidence and search-warrant material helped investigators connect Spektor to the operation. Prosecutors also alleged that his home IP address was linked to wallets that received cryptocurrency taken from victims.
Authorities recovered approximately $105,000 in cash and $400,000 worth of cryptocurrency during the investigation. The amounts represent assets seized during the probe and should not be interpreted as a final forfeiture figure.
Coinbase Helped Investigators Trace the Funds
Brooklyn District Attorney Eric Gonzalez credited the office’s Virtual Currency Unit with helping uncover the operation. He said investigators followed the digital trail, identified the person behind the scheme and assembled evidence for the prosecution.
Coinbase Chief Legal Officer Paul Grewal said the exchange assisted authorities in identifying Spektor and the customers affected by the scheme. Coinbase also provided evidence and helped law enforcement trace and recover stolen funds.
The case highlights a recurring warning for cryptocurrency users: legitimate companies such as Coinbase generally do not contact customers unexpectedly and instruct them to move cryptocurrency to a “safe wallet.”
Scammers can also manipulate caller ID, sender information and imitation websites to make fraudulent communications appear legitimate. Users should verify suspicious requests through official in-app support channels and avoid transferring cryptocurrency simply because someone claims immediate action is required.
