Bitcoin has mined 20 million coins: why the last of the remaining 1 million won’t arrive until 2140

20 millionth Bitcoin was mined, meaning >95% of the 21 million supply is mined and fewer than ~1 million remain; the final coin is expected in ~114 years and 99% will be mined by 2035 due to scheduled halvings. Miners currently receive 3.125 BTC (down from >6 BTC pre-2024 and 50 BTC at inception), and when issuance ends in 2140 miners will rely on transaction fees. Bitcoin is trading around $71,000 (about -46% from its all-time high) and has risen ~16,000% over the past decade from ~$430 in March 2016. CEO Raphael Zagury says the milestone likely won’t move prices short term (liquidity/macro dominate) but reinforces long-term scarcity and predictable monetary policy.

Analysis

The market impact of any supply story is mediated far more by exchange float, custody flows, and derivatives positioning than by headline scarcity. Small changes in the % of circulating supply available to trade—especially during low-volatility windows or stretched option gamma—can create outsized price moves; model a 1-2% shift in exchange balances translating to a multi-percent move in spot under thin liquidity conditions.

Miners’ economics will be the key second-order variable: miners that can lock long-term, low-cost power and hedge a portion of production will compress sell-side pressure and extract optionality from fee volatility. Expect accelerated consolidation among mid-tier miners, and a bifurcation where vertically integrated players or those with long-term offtake agreements outperform asset-light hosts that need to sell spot to fund opex and capex.

Macro and market-structure catalysts dominate short-to-medium term direction: macro tightening, large ETF flows, futures curve roll yield, and clustered options expiries can swamp narrative effects. Over 12–36 months, a sustained shift from block-reward-driven revenue to fee-dominant economics will favor custody, liquid staking, and infrastructure providers over pure-play spot liquidity vendors; monitor on-chain fee capture, exchange balances, and miner hedge books as leading indicators.

Key Decisions for Investors

• Long selective miners (RIOT, MARA) via 12–18 month call spreads: buy OTM call spreads to capture asymmetric upside from consolidation and reduced sell pressure while capping downside (target R/R ~3:1 if Bitcoin appreciates 50%+). Size 2–3% portfolio, hedge with 25% of notional in short-dated puts to limit drawdown risk.
• Long Coinbase (COIN) 6–12 months with downside protection: buy shares and purchase 3–6 month 30% OTM puts (protects against macro shock/regulatory selloff). Thesis: custody and flow-driven revenue should re-rate; target 40–60% upside vs capped 30% protected downside, adjust hedge cost if volatility spikes.
• Short short-term roll (contango) in Bitcoin futures via BITO on 1–3 month horizon when front-month roll >4%: implement small tactical short ETF position or sell futures roll to harvest negative roll yield. Risk: sudden spot squeezes; cap position and use stop if curve inverts or basis tightens.
• Event-driven long volatility trade: buy 1–3 month BTC straddle (or call-heavy fly) ahead of major macro prints or large expiries where gamma is concentrated. This protects against headline-driven breakouts while providing directional optionality; keep size modest (1% equity) given implied vol premia.
