CIA Deputy Director Michael Ellis says Bitcoin is pseudonymous, not anonymous, and that US intelligence uses it to collect information on adversaries. He also named drug cartels and terrorist organizations as groups whose crypto use can be tracked.
CIA Deputy Director Michael Ellis said in a May 1, 2025 podcast interview that Bitcoin is not truly anonymous and that US intelligence uses it to collect information on adversaries. The remarks challenge the early pitch of Bitcoin as digital cash that nobody could trace.
Ellis calls Bitcoin pseudonymous
Ellis described Bitcoin as pseudonymous rather than anonymous. On the network, activity is tied to addresses rather than legal names, and Ellis's point is that the gap between an address and a real person can be closed.
According to Ellis, that gap lets US authorities follow illicit activity connected to adversaries. He named drug cartels and terrorist organizations as examples of groups whose crypto use can be tracked.
He also placed Bitcoin inside a broader technology competition with countries like China. On adoption, he pointed to growing institutional interest and said, according to Ellis: "Bitcoin is here to stay."
Views with a track record inside intelligence
Ellis was sworn in as CIA Deputy Director on February 10, 2025, so his podcast remarks came less than three months into the job.
The views are not new. Former Acting CIA Director Michael Morell praised blockchain analytics tools like Chainalysis in a 2021 analysis, crediting them with helping efforts against illicit finance. The CIA also works with law enforcement to trace illicit payments made with digital assets, and Ellis's comments put a more public face on that cooperation.
Analytics firms cluster addresses on the blockchain, map flows between them and flag links to known entities. That turns a stream of pseudonymous transactions into something closer to a readable map.
What it means for holders
For holders, the most direct implication concerns privacy expectations: a CIA official has said plainly that Bitcoin transactions are not invisible to governments. The CIA's framing of Bitcoin as a national security tool may also lift institutional confidence and potentially strengthen its standing with the public and regulators.
