Tesla and SpaceX CEO Elon Musk has reignited some discussion around Bitcoin, describing it as a “fundamental physics-based currency” grounded in energy.
Speaking on a recent podcast with Nikhil Kamath, Musk emphasized that Bitcoin’s value is tied to real-world energy expenditure, highlighting a distinction between digital assets and traditional fiat currencies.
“Energy is the true currency,” Musk said. “This is why I said Bitcoin is based on energy. You can’t legislate energy. You can’t just, you know… pass a law and suddenly have a lot of energy.”
The Tesla founder drew attention to the difficulty of producing and harnessing energy, linking it to Bitcoin’s proof-of-work system, which requires substantial computational power and electricity to secure the network.
He also referenced the Kardashev scale — a method for measuring a civilization’s energy consumption — as a lens for understanding societal progress. He suggested that evaluating a civilization by its capacity to generate and manage energy mirrors Bitcoin’s design principles, where scarcity and computational effort underpin value.
Looking further ahead, Musk proposed that advancements in artificial intelligence and robotics could render money obsolete.
“In a future where anyone can have anything, I think that you no longer need money as a database for labor allocation,” he said, citing Iain M. Banks’ post-scarcity Culture series as a blueprint for societies where super-intelligent machines manage resources without monetary systems.
Musk: You can’t print energy
Musk also underscored the unique qualities of Bitcoin. Unlike fiat money, which governments can print at will, Bitcoin’s proof-of-work system ties its creation to energy and computing power, giving it a built-in scarcity and relative independence from political influence.
“Governments can print money, but they cannot print energy,” Musk said.
While Musk envisions a future where energy might serve as a more fundamental measure of value, he acknowledged that traditional money remains dominant today.
National currencies continue to govern commerce, wages, and savings, while cryptocurrencies like Bitcoin exist as alternative assets rather than replacements for everyday transactions.
Musk’s remarks provide a reminder of the philosophical underpinnings of Bitcoin, linking it to physics and energy rather than policy and government control.
Earlier today, the Bitcoin price plunged 8% to the mid-$84,000s early Monday, extending a two-month drawdown that has erased over 30% since October’s record highs.
The drop followed last week’s brief recovery above $92,500 after November lows near $81,000.
