Our Story
Founder Sascha Grumbach discovered Bitcoin in Berlin back in 2012. His exploration of the Bitcoin mining industry throughout the years revealed a troubling pattern: companies often failed to deliver on their promises of environmental responsibility. Determined to change this, in 2022, Sascha joined forces with Valentine Pleser to create Green Mining DAO, a venture rooted in sustainable, innovative, and community-focused Bitcoin mining.
From the start, Green Mining DAO set out to redefine mining practices. By harnessing hydroelectric energy, the company minimizes carbon emissions while repurposing excess heat to dry fruits, combining profitability with sustainability. Operating as a Decentralized Asset Organization (DAO), Green Mining DAO emphasizes transparency, inclusivity, and shared decision-making, embodying the decentralized ethos of blockchain technology.
Our latest flagship project, Green Mine #003 (GM3), takes this vision further. GM3 democratizes access to Bitcoin mining by offering investors Bitcoin at production cost, eliminating barriers typically associated with mining. Powered entirely by renewable energy, GM3 achieves CO2-neutral operations, ensuring minimal environmental impact while delivering long-term profitability.
