According to online reports, according to Cointelegraph's analysis, PancakeSwap claimed that the winners of its trading competition in July were randomly selected, but blockchain records show that about half of the 1700 winning wallets belong to interconnected wallet clusters. Cointelegraph's investigation found that at least 850 award-winning wallets were funded by other award-winning wallets, and these wallets transfer BNBs to each other for swipe transactions to meet threshold requirements. The representative of the League of Traders said that these wallets are directly related to each other and are all selected, the probability of continuous occurrence is close to zero, the distribution of prizes is unfair, and the winners seem to be "artificially selected" rather than randomly selected.
