The U.S. Securities and Exchange Commission’s Division of Corporation Finance issued a landmark clarification on March 20, 2025, affirming that proof-of-work (PoW) cryptocurrency mining activities do not constitute securities transactions under federal law. This decision provides long-awaited regulatory certainty for Bitcoin miners and other participants in decentralized blockchain networks.
According to the SEC’s statement, protocol mining—including solo mining and participation in mining pools—operates as an administrative or ministerial activity rather than an investment contract. The regulator emphasized that miners validate transactions and secure networks through computational effort, earning rewards in “Covered Crypto Assets” such as Bitcoin, Dogecoin, or Litecoin. These rewards do not satisfy the “efforts of others” criterion under the Howey Test, which determines whether an asset qualifies as a security.
The SEC distinguished between mining activities and securities offerings, noting that miners contribute real-world resources like hardware and electricity without relying on managerial or entrepreneurial efforts from third parties. Even miners joining pools—where participants combine computational power to improve reward probabilities—are exempt from registration requirements. Pool operators’ roles remain limited to administrative coordination rather than profit-driven management.
Industry stakeholders welcomed the clarity, which removes uncertainties lingering under former SEC Chair Gary Gensler’s tenure. Publicly traded mining firms like Marathon Digital and Riot Platforms are expected to benefit from renewed investor confidence. The announcement aligns with recent pro-crypto moves by the SEC, including exemptions for memecoins and the resolution of high-profile cases like Ripple’s XRP lawsuit.
President Donald Trump’s nominee for SEC Chair, Paul Atkins, is slated to face a Senate Banking Committee hearing next week. Observers anticipate this clarification will bolster legislative efforts to foster U.S. leadership in blockchain innovation. Meanwhile, Bitcoin’s price remained stable following the news, though mining-related stocks saw mixed trading activity.
The SEC’s guidance applies exclusively to public, permissionless PoW blockchains, with no changes to existing rules for proof-of-stake networks or securities-related fraud enforcement. Legal experts caution that mining startups resembling investment schemes, such as the defunct Green United project, may still face scrutiny.
