On-chain detective ZachXBT released an investigation stating that Spartans' so-called co-founder Gurhan Kiziloz is also the behind-the-scenes operator of the suspicious project Blockdag Network, which has raised over $300 million from retail investors through social media advertising promising unrealistic returns and false partnerships. ZachXBT pointed out that the token sale of Blockdag has lasted more than two years, during which Gurhan transferred pre-sale funds through Middle Eastern OTC channels and lavishly spent on luxury cars, mansions, and luxury watches.
