Who he is
Alex Mashinsky is an Israeli-American entrepreneur who was for two decades a respected figure in New York technology: a VOIP pioneer with foundational patents dating from the 1990s, founder of Arbinet and Transit Wireless (the Wi-Fi of the New York subway), twice named entrepreneur of the year by Ernst & Young. In 2017 he founded Celsius Network, a crypto lending and yield platform that grew to around 20 billion dollars in assets under the slogan "Unbank yourself". In July 2022 Celsius froze withdrawals and went bankrupt, revealing holes and reckless bets with customer funds. Today his name is tied to one of the largest frauds in the sector's history: he pleaded guilty and is held in a US federal prison.
Current role
Held in federal prison in the United States. (Verified: September 2026) Mashinsky resigned as CEO of Celsius in September 2022, was arrested in July 2023 and in December 2024 pleaded guilty to two counts: commodities fraud and manipulation of the CEL token price. On 8 May 2025 judge John Koeltl (Southern District of New York) sentenced him to 12 years in prison, with forfeiture of 48 million dollars and several properties. He holds no active corporate role.

Recent developments and controversies
- Criminal conviction (Verified: September 2026): 12 years for fraud, between the defence's request (one year and one day) and the prosecution's (20 years). The judge described the crimes as "extremely serious"; the prosecution portrayed him as a predator who "preyed on hope" of small savers.
- The collapse of Celsius: the July 2022 bankruptcy locked up the funds of hundreds of thousands of customers. The insolvency proceedings began partial distributions to creditors in subsequent years; the events of summer 2022 remain one of the emblematic cases of that year's crypto "contagion", alongside FTX.
