# Infinite Economic Half-Life

## Definition

The property of an asset — like [[entity-bitcoin]] — to retain its purchasing power indefinitely because its supply inflation rate asymptotically approaches zero.

## The half-life concept

[[entity-michael-saylor]] introduces **economic half-life** as the timeframe over which an asset's purchasing power gets cut in half by supply expansion.

- **Gold**: ~2% annual supply growth from mining → ~36-year half-life. Wealth stored in gold loses half its value over ~36 years.
- **Fiat currencies**: printed at much higher rates → much shorter half-lives. See [[claim-fiat-goes-to-zero]].
- **Bitcoin**: hard cap of 21M coins, inflation rate asymptotically approaching zero → **infinite** economic half-life.

## The immortality metaphor

Saylor frames this as the difference between mortal and immortal wealth. See [[quote-immortality-zero-inflation]]: *"Zero is a billion trillion years, you're a god. 2% is you're going to die... half of you dies in 36 years."*

An asset with a finite half-life means your wealth will eventually "die." An asset with an infinite half-life grants **economic immortality**, allowing wealth to persist and grow indefinitely.

## Why it underpins the rest of the thesis

This concept is the mathematical scaffolding behind [[concept-digital-capital]] and the comparison in [[claim-gold-is-inferior-to-bitcoin]]. It also explains why Saylor sees [[claim-traditional-credit-is-broken]] — bond yields below monetary inflation guarantee a finite, declining half-life on fixed-income holdings.

## Enrichment / expert nuance

- The mechanics (gold ~1–2% mine supply growth; BTC capped at 21M with halving issuance) are factually accurate per industry and protocol documentation.
- The framing leans on Austrian / hard-money / stock-to-flow logic, which mainstream academic finance treats as contested.
- A long-term store of value depends not only on supply but also on **demand stability, legal/regulatory treatment, and market microstructure** — dimensions on which BTC's case is still developing.
