“Four years ago when I started this job, there were some people that just thought this thing was all going to blow up and go away, that this was sort of a passing fad,” said Kristin Smith, executive director of the Blockchain Association, a trade group representing crypto firms.

Now, she said, “We’ve got all these regulators suddenly vying for control.”

At the heart of the turf war are questions about how cryptocurrencies fit into the definition of a security, the legal classification that includes stocks and bonds.

Firms such as Coinbase, FTX and Ripple have spent millions of dollars over the past year lobbying Congress to create a new category for digital commodities and empower the CFTC to regulate it. The agency has roughly one-sixth the head count of the SEC, and its rules are seen by the industry as easier to comply with than securities laws.

It would require any entity acting as a digital commodity platform—including crypto exchanges such as Coinbase and FTX—to register with the CFTC as trading facilities, dealers or brokers. The exchanges would have to monitor trading, protect investors from abuse and only offer assets that are resistant to market manipulation, among other requirements.

If the agency wins jurisdiction over bitcoin and ether, the CFTC would have to write rules from scratch to protect such investors.
