Stephen Cole on Castle, Bitcoin Treasuries, and Fixing Business Money

Bitcoin isn’t just a hedge anymore—it’s becoming a foundational tool for businesses trying to survive inflation, rising costs, and a broken monetary system. In this episode, Brandon Karpeles sits down with Stephen Cole, long-time Bitcoiner, investor, community builder, and now co-founder & CEO of Castle, a Bitcoin treasury platform built specifically for businesses.

Stephen brings decades of experience across Silicon Valley, startups, and Bitcoin.

He breaks down:

- How he went from Silicon Valley engineer to Bitcoin educator and venture investor
- Why businesses are suffering under the current monetary system
- Why merchant adoption has been painfully hard for a decade
- Why store of value first is the correct Bitcoin adoption sequence
- How Castle lets businesses automatically convert a percentage of revenue into Bitcoin
- Why small businesses are being crushed—and how Bitcoin levels the playing field
- The connection between Bitcoin, inflation, U.S. manufacturing, and American prosperity
- Why Bitcoin is actually more American than the modern U.S. dollar
- What early Bitcoin adoption looked like in 2013—and why business adoption in 2025 feels the same way
- How companies from restaurants to law firms are already quietly stacking sats through Castle

This episode is a deep, practical, and philosophical discussion about broken money, American industry, long-term business health, and why Bitcoin is rapidly shifting from “weird fringe idea” to “standard treasury practice.”Castle is building one of the most important tools in the Bitcoin business ecosystem—and Stephen explains exactly why.
