Trust, but verify: The economics of scams in initial coin offerings

Losses from frauds and financial scams are estimated to exceed U.S. $5 trillion annually. To study the economics of financial scams, we investigate the market for initial coin offerings (ICOs) using point-in-time data snapshots of 5,935 ICOs. Our evidence indicates that ICO issuers strategically screen for na¨ıve investors by misrepresenting the characteristics of their offerings across listing websites. Misrepresented ICOs have higher scam risk, and misrepresentations are unlikely to reflect unintentional mistakes. Using on-chain analysis of Ethereum wallets, we find that less sophisticated investors are more likely to invest in misrepresented ICOs. We estimate that 40% of ICOs (U.S. $12 billion) in our sample are scams. Overall, our findings uncover how screening strategies are used in financial scams and reinforce the importance of conducting due diligence.
