Today we @crypto_council @TeamPOSA — with 30+ leading orgs — submitted a letter urging the SEC to clarify that staking is a technical process, not a securities activity. We are aligned across the industry. The time for clarity is now.

We at @TeamPOSA have been advocating for proper tax treatment of staking (and mining!) rewards for years. Ensuring that staking does not give rise to UBTI would pave the way for staking in ETPs. Let’s get this done.
