According to data from Chainalysis, over half of the tokens launched on Ethereum in 2023 were involved in pump and dump schemes, where insiders manipulate the market for profit. However, these tokens only made up 1.3% of total trading volume on decentralized exchanges. The permissionless nature of Ethereum allows anyone to create an ERC-20 token and trading pool, leading to potential fraudulent activity. Chainalysis suggests that this highlights the need for education on how to search for suspicious on-chain activity.
