But Klyuka's life took a nightmarish turn one day in February 2023 when he was arrested by masked members of Russia's feared FSB security service. He was accused of sending 135,000 rubles (around $1,380) in cryptocurrency to Ukraine's ultranationalist Azov brigade, classified as "terrorist" in Russia -- a charge he denies.
