According to data from blockchain security company BLOCKAID, 50% of the presale tokens launched in the SOLANA ecosystem between November last year and February this year exhibited malicious behavior. These malicious activities include exploiting users' FOMO emotions, imitating legitimate transactions, and creating deceptive websites, among other strategies. IDO BEN-NATAN, co-founder of BLOCKAID, pointed out that the popularity of legitimate meme coins and the complex strategies employed by scammers are key factors contributing to the spread of scams. Additionally, the popularity of meme coins and the activity of algorithmic trading bots have also affected the transaction processing performance of SOLANA.
