Prosecutors had asked for Thodex boss Faruk Fatih Ozer, 29, to be sentenced to 40,562 years in prison for money laundering, fraud and establishing a criminal organization.
“If I were to establish a criminal organization, I would not have acted so amateurishly,” Anadolu quoted Ozer as telling the court.
His two brothers, Serap and Guven, received the same sentence, which was issued late Thursday after a brief trial, Turkish media reports said.
Turkey is known for issuing massive prison sentences, which became the norm after it abrogated the death penalty in 2004 to help its efforts to join the European Union.
Ozer was initially reported to have fled Turkey in April 2021 with $2 billion in investor assets, although that figure has since been disputed.
Prosecutors said Ozer had transferred 250 million liras in user assets (worth about $30 million at the time) to three secret accounts when he fled Turkey in April 2021, with much of the money ending up in a Malta bank.
The indictment said the Ozer brothers had caused 356 million liras of damage to clients in all.
The case grabbed local headlines because it coincided with a Turkish crypto boom that has since largely subsided due to heavier government regulation.
Turks began turning to various cryptocurrencies as a defence against a deep slide in the value of the lira that began more than two years ago.
Ozer gained further celebrity status after being pictured meeting with ultranationalist pro-government figures.
He was arrested last year in Albania on an international arrest warrant from Interpol.
