On-chain detective ZachXBT released an investigation stating that Gurhan Kiziloz, the so-called co-founder of Spartans, is also the behind-the-scenes operator of the suspicious project Blockdag Network, which promised unrealistic returns and false partnerships through social media advertising, raising over $300 million from retail investors. 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.
