If you take a look around, you’ll notice that @bittensor_ investors (especially the early adopters), appear to be operating at the confluence of cosmic and intellectual curiosity. Coincidence? I think not. Unseen forces at work? I think so. Prediction? Big. Very very big. $TAO

Mark Jeffrey @markjeffrey, Partner at @stillcorecap, joins Proof of Talk 2026 as a speaker this June. He wrote the book on Bitcoin, and is now deploying capital into what he believes is the next foundational layer of the internet. Stillcore Capital is an open-end, evergreen hedge fund focused on Bittensor, subnet alpha tokens, and decentralized AI opportunities across the Bittensor ecosystem. The fund publicly targets roughly 1% of TAO's liquid supply and combines capital deployment with active ecosystem participation. Mark is a serial entrepreneur and early Bitcoin adopter. He co-founded The Palace, ZeroDegrees, and Guardian Circle, and hosts Hash Rate, a research-driven show covering Bittensor, AI, and crypto. He is also the author of Bitcoin Explained Simply and The Case for Bitcoin. At Proof of Talk on June 2–3, he joins the builders and allocators who are making the same kind of early bets on decentralized AI that he made on Bitcoin fifteen years ago.
