In 2024, the U.S. Securities and Exchange Commission (SEC) reached a significant milestone in its enforcement actions in the cryptocurrency sector, initiating a total of 33 enforcement actions with fines totaling $4.98 billion, primarily targeting fraud, unregistered securities offerings, and NFTs. This marks a shift for the SEC from its previous focus on ICOs to more complex DeFi and staking operations. Although the total number of enforcement actions decreased by 30% compared to 2023, the amount of fines increased significantly, largely due to the $4.55 billion settlement with Terraform Labs. The SEC took action against NFTs for the first time, accusing them of conducting unregistered securities offerings and showing increased concern for institutional participants, with enforcement actions against companies making up 43% of the total in 2024. Despite increased regulatory pressure, DeFi activity demonstrated strong resilience, with monthly transaction volume continuing to grow in 2024, reaching nearly 200 million transactions. The cryptocurrency market reacted positively to regulatory clarity, with a total market capitalization of $3.50 trillion and a trading volume of $147.30 billion, indicating market maturity and growth under regulation. The SEC's enforcement strategy is evolving towards more complex market areas, particularly in DeFi and staking services.
