Xellox Joins BTCHEL 2025 as Official Partner and Speaker

 

As Bitcoin takes the stage in Helsinki, Xellox steps forward to support innovation, sovereignty, and security.

Xellox is proud to announce its role as an official partner of the BTCHEL CONFERENCE 2025, one of the most anticipated Bitcoin-only events in Europe this year. Taking place in Helsinki, Finland this August, BTCHEL will gather leading thinkers, builders, investors, and plebs under one roof to explore the future of decentralized money.

Among the many highlights: Samuel Harjunpää of Xellox will take the stage not once, but twice, bringing insight into secure Bitcoin self-custody, seed protection, and the real-world challenges facing hodlers today.

BTCHEL isn’t just another crypto expo. It’s a mission-driven, Bitcoin-only gathering that emphasizes long-term thinking, individual freedom, and resilience in an increasingly centralized world. With themes such as Energy, Circular Economies, Privacy, Community, Mining, and Self-Custody, the event aligns perfectly with Xellox’s vision: building practical tools for Bitcoiners who demand real-world security.

Other confirmed speakers include Martti Malmi (early Bitcoin developer), Mikko Hyppönen (Chief Research Officer, Sensofusion), Allen Farrington, Knut Svanholm, Anita Posch, Christian Keroles (CK Snarks), and Wiz – each bringing unique perspectives on Bitcoin adoption, sovereignty, and freedom tech.

Why Finland? As BTCHEL highlights, the country combines Bitcoin-friendly policy, clean energy, and a digitally advanced society that respects privacy and innovation. For Xellox, Helsinki is the ideal stage for pushing forward the conversation on real, secure self-custody.

Attendees can also visit Xellox’s booth at the venue to learn more about our product lineup, including the secure Xellox SEED backup system and the upcoming CLAVIS signing device.

BTCHEL marks a new chapter for the Nordic Bitcoin community, and Xellox is thrilled to be part of it.
