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 more common after it abolished 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.
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.
