A California man has been sentenced to 70 months in prison for his role in stealing over $263 million worth of Bitcoin. The case details a highly organized crypto crime ring that spanned multiple states and relied on both digital infiltration and physical hardware wallet theft.
The syndicate: from gaming friends to specialists
According to court documents, the group formed through online gaming communities. Members came from California, Connecticut, Florida, New York, and overseas. Roles included database hackers, organizers, target scouts, impersonators posing as exchange or Google support staff, and individuals who physically seized victims’ hardware wallets.
Using aliases like “E,” “Tate,” and “Evan|Exchanger,” Tangeman admitted to laundering at least $3.5 million in stolen crypto into cash, and renting luxury homes under fake identities for operations.
The heist: 4,100 BTC from one victim
In August 2024, the group stole more than 4,100 Bitcoin from a single victim in Washington, D.C.—worth about $230 million at the time, now over $321 million. Blockchain researcher ZachXBT publicly identified suspects, including Malone Lam and Jeandiel Serrano, leading to swift federal arrests.
U.S. Attorney Jeanine Ferris Pirro called the scheme “driven by greed and executed with almost cartoonish audacity.” Stolen funds fueled nightclub bills, luxury cars, and expensive watches. Tangeman also instructed associates to destroy evidence after some arrests, showing consciousness of guilt.
Luxury lifestyle exposed: Rolls-Royce, Porsche, $80K monthly rent
Searches of Tangeman’s residence uncovered a 2022 Rolls-Royce Ghost and a Porsche GT3 RS. Indictments allege Lam bought a Lamborghini Urus registered in Tangeman’s name. Some members rented mansions in Los Angeles, the Hamptons, and Miami, paying $40,000 to $80,000 monthly rent.
Wider investigation: three new suspects added
After Tangeman’s guilty plea, three new defendants—Nicholas Dellecave, Mustafa Ibrahim, and Danish Zulfiqar—were added. The FBI and IRS Criminal Investigation teams continue probing. Tangeman also received three years of supervised release. The DOJ stressed these organized digital asset crimes may have international links, urging investors to secure hardware wallets.
