◆ Core investigation
Sinteza Invest Group → TradeWin24
The same people who bankrupted Sinteza Invest Group in 2016 through client manipulation and insider trading founded a new brokerage under a new name in 2018. The Securities Commission did not stop this step, despite violating its own rules.
TradeWin24 was later taken over by Oleg Boyko through an ownership structure passing through two Cypriot offshore companies: Tirona Ltd and Ficron Finance Limited. The goal: insert suspicious capital into Serbia’s financial system while regulators look away.

Who is Oleg Boyko?
Oleg Boyko is not just “another” Russian businessman. His path to wealth is shadowed by scandals, allegations, and politically sensitive ties that placed him on Western blacklists. Boyko appears on blacklists in Australia, Canada, Poland, and Ukraine — his name is tied to suspicious offshore transactions, and his companies have faced investigations around the world.
According to a 2017 US intelligence report delivered to the Senate, Boyko was described as “a person with troubling ties to the Russian government, Russian intelligence and security services, as well as organized crime.”
To public astonishment, by decision of the Government of Serbia, Boyko was granted Serbian citizenship in March 2025.
Why Serbia?
Serbia has not imposed sanctions on Russia and has not fully aligned its regulatory framework with AMLD5 and AMLD6 EU anti-money-laundering directives. That makes it accessible, regulatorily softer, and ideal for the “placement” of capital that would face scrutiny in the EU.
Erglis Property Kft — the Hungarian connection
The investigation also identified the Hungarian company Erglis Property Kft, appearing as a potential financial pass-through entity within the wider Boyko network, with a mixed Russian-Hungarian registration footprint — pointing to a coordinated structure for transferring funds across multiple EU jurisdictions.
Modus Operandi
How the scheme works01
Attracting investors with false conditions
TradeWin24 offers “incredibly favorable” commissions and direct access to global exchanges. The advertised fee schedule has nothing to do with the real costs.
02
Taking money under a false “segregation” claim
The broker takes money while claiming it is technically “segregated” — yet retains full access to the account.
03
Manipulating results and Ponzi rotation
When the client wants to withdraw funds, they are informed that they “suffered a loss.” A classic Ponzi pattern.
04
Extracting capital through dividends
Before collapse, owners pay themselves huge dividends using client funds.
05
Rebranding and starting over
The same people open a new firm under a new name. Sinteza Invest Group becomes TradeWin24. The cycle begins again.
