Bitcoin At Zero

Same exercise in the other direction. Bitcoin going to zero would require something genuinely catastrophic — but it’s worth knowing what that actually looks like.

A cryptographic break. If a sufficiently powerful quantum computer or another breakthrough made it possible to derive private keys from public keys, Bitcoin’s security foundation would collapse. Funds could be stolen. Trust would evaporate. This is the most technically plausible path to zero.

The Bitcoin community is aware of this and has been working on quantum-resistant cryptographic schemes for years. The threat is real but not imminent — and the protocol could theoretically migrate to new cryptography before existing wallets were compromised, if the community moved fast enough. Whether it would is an open question.

A critical software vulnerability. A flaw in Bitcoin Core that allowed arbitrary coin creation, double-spending, or network shutdown. This has happened in a much smaller form — a 2010 bug briefly created 184 billion Bitcoin before being patched within hours. A more severe, less quickly-patched version could be devastating.

Coordinated global suppression. Every major government simultaneously banning Bitcoin, criminalising its use, and destroying the infrastructure that supports it. This is practically implausible — different countries have completely different interests, but it can’t be mathematically excluded.

Complete loss of interest. If the entire world simply stopped caring and stopped mining, the network would wind down. Given the trajectory of adoption over fifteen years, this seems the least likely scenario.

Bitcoin going to zero requires something genuinely systemic. It’s not impossible. It’s just considerably less likely than the price charts in 2018, 2022, and every other crash implied.

Tomorrow: the patience premium — what holding through cycles has historically paid.
