Total Supply Approaches 21,000,000
By 2030, over 97% of all Bitcoin that will ever exist will already have been mined. The remaining 3% will trickle out over the following 110 years. We are witnessing the last generation where significant amounts of new Bitcoin enter circulation.
Add up each halving era and you get a series that approaches (but never exceeds) 21 million BTC. Practically, nearly all coins are issued within the first few decades.
Simple series intuition:\n\nPer era coins ≈ 210,000 × Reward(k).\nSince Reward(k) halves each time, the total is a shrinking series that converges near 21,000,000.
Milestones (approximate):\n\n• 2009–2012: 50 BTC era → big jump in supply\n• 2012–2016: 25 BTC era\n• 2016–2020: 12.5 BTC era\n• 2020–2024: 6.25 BTC era\n• 2024–2028: 3.125 BTC era\n\nEach step adds fewer new coins than the last.
The asymptotic approach to 21 million means every Bitcoin gets relatively scarcer over time. Early adoption has a mathematical advantage that becomes more pronounced with each halving.
