Proof-of-work converts energy into monetary security, and Willy Woo argues that makes Bitcoin the strongest hard money ever constructed. On April 7, 2026, the on-chain analyst laid out his energy rebuttal on X. One of his implicit targets was economist Steve Keen, who predicted the 2008 financial crash, and now warns that Bitcoin will go to zero.
Woo’s framing cuts directly against the mainstream critique that Bitcoin’s energy consumption is wasteful or unjustifiable. Operators like Gridless mine Bitcoin on stranded renewable energy from rural mini-grids across Kenya, Malawi, and Zambia – power that would otherwise go to waste. The revenue funds grid expansion into communities that the national grid has never reached.
“BTC uses too much energy.”
There’s only 3 ways to secure a monetary ledger.
– with atoms (gold)
– with energy (BTC)
– with social / political consensus (fiat)Energy is the only path to unbreakable hard money. There’s no scarcity of atoms.

Woo structures his case around three models of monetary security. Gold is secured by atomic scarcity, fiat by social and political consensus, Bitcoin by energy. His argument for energy’s superiority draws directly on the Kardashev Scale, the framework measuring civilizational energy consumption.
Every joule unlocked by technological progress gets absorbed into economic competition immediately. Homes, factories, transport, and industry all compete for available power. Staging a 51% attack on Bitcoin, therefore, requires capturing roughly half of global energy output. It would simultaneously collapse every economy dependent on that power, making the attack self-defeating at any civilizational scale.
Incorrect – study Kardashev Scale.
For every joule of energy that can be unlocked, the energy will compete for economic use. Hence to break BTC you need to capture 50% of available energy.

Woo also dismissed proof-of-stake as a true alternative. He described it as a concealed form of social consensus, where insiders distribute coins and retain control through staking nodes.
POS is a stealth social concensus. Insiders distribute the coins, they then promote the coin and control the concensus via staking nodes.
Some exceptions like Decred which used PoW + PoS.
ETH which used PoW to distribute is less but still lots of early pre-seed buyers holding…

In a follow-up post around two hours later, Woo pushed the argument into economic theory. He argued that GDP and energy consumption track each other directly. The only mechanism capable of securing hard money is energy, always scarce because the entire economy competes for every available unit.
Very few economists understand thermodynamics and physics.
The economy is an engine turning raw materials and energy into goods and services.
A country’s GDP = energy consumption.
The only way to secure hard money is with energy. Because energy is competed for by the economy…

Gold’s scarcity depends on the limits of atomic extraction. Space rockets at scale or nuclear fusion capable of transmuting atoms would erode that moat permanently. Bitcoin enforces issuance algorithmically, with security that scales alongside economic energy competition, not against it.
The 2025 Cambridge Digital Mining Industry Report estimated Bitcoin’s annual electricity use at 138 TWh, roughly 0.5% of global consumption, up 17% year-on-year as the network’s hashrate climbed.
While Woo’s argument focuses on Bitcoin’s consensus-layer security, it doesn’t fully address risks at the cryptographic layer. In February 2026, he acknowledged that Bitcoin’s 12-year performance trend against gold had broken, attributing part of it to market pricing in quantum risk.
12 YR TREND BROKEN.
BTC should be a valued a LOT HIGHER relative to gold.
Should be. IT'S NOT.
The valuation trend broke down once QUANTUM came into awareness.

Bitcoin’s ECDSA signature scheme is the real exposure point – Shor’s algorithm could theoretically derive private keys from exposed public keys. Most forecasts place credible risk in the 2035–2045 window.
Around 4 million lost BTC in older address formats represent a specific structural vulnerability. Woo put the odds of those coins not being frozen in a future hard fork at 75%, leaving a supply shock overhang he said could persist for 5-15 years.
Likely, BTC will be patched with quantum resistant signatures. This doesn't fix the issue of 4M lost coins coming back into circulation.
I'd say it's 75% chance that lost coins will not be frozen by a protocol hard fork.
— Willy Woo (@willywoo) February 16, 2026
Bitcoin’s adaptability through protocol upgrades offers a path forward, with the current community roadmap favouring a phased migration over a hard fork, but governance disagreements over freezing vulnerable coins remain unresolved.
