The fixed supply cap of 21 million Bitcoin means mining will eventually exhaust all coins by approximately 2140. This raises a critical question: what will one Bitcoin be worth when the final coin is mined 120 years from now?
Forecasting Bitcoin's Long-Term Value
To project Bitcoin's future price, analysts use two primary growth models:
- Parabolic Super Trend Growth Model
- Stock-to-Flow (S2F) Price Model
Even under "hyperbitcoinization" — where Bitcoin dominates global finance — its price won’t reach infinity. Early Bitcoin contributor Hal Finney estimated a $10 million per BTC valuation by comparing global household wealth (~$360 trillion) to Bitcoin's capped supply. Research firm Decrypt projected an $18 million/BTC ceiling assuming no superior alternative assets emerge.
Parabolic Super Trend Growth Model
Since Martti Malmi executed Bitcoin's first fiat trade in 2009, BTC has appreciated by 223,211,101.11%. Its price trajectory mirrors the S-curve adoption pattern seen in transformative technologies like the internet and smartphones, suggesting accelerated future growth.
Stock-to-Flow Price Model
This metric calculates how many years current production would need to replicate existing supply. Key insights:
- Gold's S2F: 62 years
- Bitcoin's Current S2F: 25 (pre-halving) → 50 (post-2024 halving)
Historical data shows BTC price surges align with halving events. Digitalik.net forecasts $1,215,730.5 per BTC by 2025 using this model.
Revised Price Projections
| Metric | Calculation | BTC Price Estimate |
|---|---|---|
| Global Household Wealth | $360T ÷ 21M BTC | $17,142,857 |
| Adjusted for Lost BTC (4M) | $360T ÷ 17M BTC | $21,176,470 |

Investment Scenario: A $100 Bitcoin purchase at $8,880 today could grow to ~$238,373 by 2140 based on these models.
FAQs
Q: Why can't Bitcoin's price grow infinitely?
A: Even with mass adoption, its value is constrained by global wealth distribution and utility demand.
Q: How accurate are S2F predictions?
A: While historically aligned with bull markets, external factors like regulation can alter trajectories.
Q: What happens to miners after the last Bitcoin is mined?
A: Transaction fees will replace block rewards as their primary revenue source.
