Alex Mashinsky is a 57-year-old entrepreneur who is accused of bilking investors out of billions of dollars. Mashinsky has portrayed himself as a modern-day Robin Hood, and is the founder of Celsius Network, a crypto lender that prosecutors allege was losing hundreds of millions of dollars in risky investments. The New York Attorney General's lawsuit seeks to ban Mashinsky from doing business in New York and have him pay damages, restitution, and disgorgement.
