Ziemian was wanted on international warrants from Poland and South Korea. FutureNet, which was established in 2018 and purported to be a crypto trading platform, is alleged to have defrauded numerous people of a combined $21 million. Victims were encouraged to buy "participation packages", and earn rewards for referring others to the scheme. Polish authorities warned that FutureNet might be a pyramid scheme in 2019, and South Korea began an investigation into the company in 2020.
Ziemian faces fraud, money laundering, and theft charges, which could be punished by life imprisonment in South Korea.
