Bitcoin Miners Must Control Their Own Power

Fred Thiel, CEO of Marathon Digital Holdings (MARA), stated in a recent interview that the future of Bitcoin mining depends on having access to independent energy sources. Without that step, he warned, miners risk losing their competitive edge, and the entire industry may face a major strategic shift.

Thiel emphasized that energy costs have become the biggest challenge for cryptocurrency mining companies. With rising competition and growing energy demand from sectors like artificial intelligence and data centers, electricity prices continue to climb. In this environment, controlling one’s own power supply is not just an advantage — it’s becoming a necessity.

Marathon is already putting this philosophy into practice. The company has launched a pilot project to produce 25 megawatts of its own power near shale gas fields in the United States — the first time in its history that Marathon has generated electricity to power its mining operations. The next step was the acquisition of a 114-megawatt wind farm in Texas, which will help reduce the company’s reliance on external energy providers and lower operational costs.

According to Thiel, companies that fail to invest in energy independence risk falling behind. The traditional model of purchasing electricity from the grid is becoming increasingly costly and uncertain amid growing demand. Owning power generation assets could soon become a barrier to entry for new players — and for established miners, a key to long-term stability and profitability.

Thiel added that energy control is not only about reducing costs but also about ensuring operational security. As competition intensifies between the crypto mining and AI industries, those that secure their own power supply will be better positioned to remain profitable, even as block rewards decrease and network costs rise.
