Mr. Slemp is a longstanding entrepreneur with success rooted in the technology sector. Having first interfaced with Bitcoin near its inception, he transitioned to full-time focus on Bitcoin as a career pursuit beginning in 2015, establishing himself as an early ecosystem participant with over a decade of dedicated involvement.
He was an early pioneer in developing grid balancing strategies with utilities through Bitcoin mining and is likely one of the only mining operations to have received a government grant for doing so. This deep operational knowledge of Bitcoin's production economics, combined with a deep philosophical conviction for Bitcoin, creates the foundation for success at BTC Management.
With over 35 years of proven leadership as an Operations Manager, Mr. Schreiner brings a wealth of experience in P&L oversight, strategic growth, and delivering consistent, profitable results across multiple industries. He offers both seasoned business insight and a strong understanding of regional economic trends.
Mr. Schreiner is known for his principled decision-making, strong conviction, and commitment to integrity—all qualities that guide his approach to modern asset management, including emerging digital assets such as Bitcoin. His Bitcoin deep dive occurred in the winter of 2020 when he encountered the solution to the fiat dilemma. After several months of discovery, he came to the conclusion that Bitcoin is the most sound money the world has ever known and changed his financial trajectory to focus on the universe's most pristine asset.
Mr. Schreiner provides strategic guidance on Bitcoin investment strategies, drawing from his extensive operations management background and deep conviction in Bitcoin as sound money. Married for 40 years and a father of four, he brings a balanced, disciplined perspective to navigating today's evolving financial landscape.
