Willy Woo Weighs In on Bitcoin Standard's Impact on Growth

Bitcoin (BTC) analyst Willy Woo has responded to a challenge economist Saifedean Ammous put forward back in 2019. Woo contends that Bitcoin's capped supply makes borrowing more hazardous, and that could curb economic expansion.

Ammous, who wrote The Bitcoin Standard, shared his original post again on X. He says he remains waiting for an economist to articulate clearly why a currency with a hard cap would fail. His 2019 post asked for something beyond "snarky eyerolls." Still, the most thorough reply up to now came from a crypto analyst rather than an academic.

Why Would Bitcoin’s Fixed Supply Hold Back Lending?

It reduces the ability for the economy to borrow to fuel productivity expansion because the currency mooning in value increases the risk that debtors will be unable to pay back.

(The current debt for economic growth example is the global borrowing to fuel AI infrastructure)…

Woo links Bitcoin's fixed supply directly to debt. When a currency keeps appreciating, borrowers must repay loans with money that becomes more expensive. Consequently, the likelihood of default rises, and lenders pull back.

He cites current worldwide borrowing for AI infrastructure as a case of debt-driven growth. Some investors are already cautioning that the AI data center boom might finish in a crash.

History offers a comparison. Under the gold standard, he observes, the ratio of paper money to gold backing was raised to ease lending risk. That move kept credit flowing on top of a scarce reserve asset.

Slower Growth or Fewer Bubbles?

Woo does not portray the cost of Bitcoin's fixed supply as purely negative. A Bitcoin standard using satoshis, Bitcoin's smallest unit, would probably deliver much slower expansion. Yet it would also produce far fewer bubbles, he says.

One user countered that savings build capital from the bottom up. Woo disagreed, saying growth depends on technology, energy and raw materials. Those demand mega-scale infrastructure and large pools of capital.

An economy grows by applying increasing tech to harvest more raw materials and more energy to produce goods and services at an increasing scale.

Tech, energy and materials is not a bottom up endeavor. They are mega scale infrastructures leveraging large pools of capital.

Woo has previously argued that Bitcoin might follow a 6-8 year debt cycle.

The exchange reignites an old split. Bitcoin supporters often point to the dollar's lost purchasing power as the argument for hard money. Critics, by contrast, view Bitcoin's fixed supply as a drag on credit.

Woo's answer suggests both sides are describing the same mechanism from opposite viewpoints. The real issue is whether a sats-based economy would trade faster growth for fewer bubbles.
