​Bitcoin mining today looks very different from what it was a decade ago. What began largely as a hardware race has evolved into a complex global industry shaped by energy markets, infrastructure development, and new demands on data centers. Companies that adapt to this new reality don’t just survive. They position themselves to lead the next phase of the industry. 👉 [RSVP on Luma](https://luma.com/cmlndtin) In this panel, executives from publicly traded mining companies will discuss how their strategies reflect this new frontier. From hardware innovation and home mining to heat reuse, large-scale energy infrastructure, and the growing intersection with AI and high-performance computing. The conversation will explore how the industry has changed, where it is headed, and why these companies remain committed to building in Bitcoin. **Guest Speakers** * ​James Cheng (CFO, Canaan Inc.): A seasoned finance leader with over 20 years of experience at Fortune 500 companies, James oversees the financial strategy for a major NASDAQ-listed hardware pioneer, focusing on investor relations and debt/equity financing. * ​Darcy Daubaras (CFO, HIVE Digital Technologies): A strategic financial expert and Corporate Director, Darcy leads global growth for HIVE, specializing in public company regulatory reporting and the intersection of crypto mining with high-performance computing. * ​Elizabeth Frei Duchek (Government Relations, Bitdeer): With over 15 years of experience in government affairs and policy analysis, Elizabeth leads government relations for Bitdeer (NASDAQ: BTDR). Her background in appropriations and public policy brings a critical perspective to how regulation, infrastructure, and energy policy intersect with the future of Bitcoin mining. 👉 [RSVP on Luma](https://luma.com/cmlndtin)​ **About the Bitcoin District Initiative** This event was organized by The Bitcoin District Initiative, a 501(c)(3) nonprofit working to build a grassroots Bitcoin circular economy in Washington, DC through education, business onboarding, and community outreach programs.

This 1967 film is widely regarded as one of the best American movies ever made. Now remembered almost as much for its Simon and Garfunkel music as its deadpan comedy and being the role that established Dustin Hoffman as the hottest actor in Hollywood. It became a cultural icon for capturing the spirit of 60s angst of a young man on the make, while garnering a batch of Oscar nominations. After watching the movie on your own, join us to relive (or experience!) those feelings at our discussion.
