For years, Washington has been debating who gets to regulate cryptocurrency. The Securities and Exchange Commission (SEC) says many tokens are securities, like stocks, and should fall under its authority. The Commodity Futures Trading Commission (CFTC) says many are commodities, like gold, and belong in its jurisdiction. The crypto industry, caught in the middle, calls the whole thing a mess. Now, a new study, "The Differential Diffusion of Exchange and Utility Value Blockchain Tokens," published in Information Systems Research, offers something rare in this debate: hard data that could help draw the line.
