Bitcoin’s circulating supply crossed 20,000,000 BTC on March 9, 2026, leaving 1,000,000 coins scheduled for issuance under the protocol’s fixed 21,000,000 supply cap.
TLDR
- Bitcoin supply reached 20,000,000 BTC at block height 939,999 on March 9, 2026, representing 95.23809% of total protocol supply, according to Bitcoin network ledger data.
- Glassnode recorded 2,104,382 BTC in exchange reserves on March 14, 2026, reflecting sustained liquidity compression across centralized trading venues.
- Bitcoin miners currently receive 3.125 BTC per block, with the next reward reduction scheduled for April 2028.
- Chainalysis estimates 3,790,000 BTC remain permanently inaccessible due to lost private keys.
- Asset manager BlackRock reported 487,256 BTC held in its spot Bitcoin ETF vehicle as of March 13, 2026.
Bitcoin Supply Passes 20 Million BTC
Blockchain ledger data confirms 20,000,000 BTC entered circulation at block height 939,999 on March 9, 2026. The remaining 1,000,000 BTC will enter circulation under the protocol’s halving-based emission schedule.
Bitcoin’s supply curve follows deterministic issuance rules encoded in the network’s consensus protocol. Each halving cycle reduces block rewards by 50%, compressing new supply generation across multi-year intervals while maintaining the fixed 21,000,000 BTC terminal cap.
Research published March 13, 2026 by U.S.-based digital asset firm River Financial states that Bitcoin’s scarcity framework derives from algorithmic issuance controls embedded in the protocol. Market price movements and mining hash rate expansion do not alter supply parameters.
Annual Bitcoin supply expansion now measures 0.9%, according to River Financial analysis released March 13, 2026. The World Gold Council estimates gold’s annual supply growth between 1.5% and 2.0%, placing Bitcoin in a lower inflation category than traditional commodity money.
Institutional Bitcoin Accumulation
Asset management firm BlackRock disclosed 487,256 BTC held within its U.S. spot Bitcoin ETF structure on March 13, 2026, according to regulatory filings.
ETF flow data shows institutional investment vehicles accumulated 12,480 BTC during the first week of March 2026. Exchange-traded products represent one of the primary accumulation channels for institutional capital entering digital asset markets.
BitInfoCharts blockchain analytics data from March 14, 2026 indicates addresses holding more than 1,000 BTC control 68.4% of the total circulating supply. The dataset classifies these wallets as high-net-worth entities and institutional custody structures.
Custodial accumulation removes coins from active trading liquidity. Each BTC transferred into institutional custody reduces the supply available for immediate market transactions.
Exchange Liquidity Compression
Blockchain analytics provider Glassnode reported 2,104,382 BTC held across centralized exchanges on March 14, 2026.
Exchange balances represent the liquid supply available for short-term trading activity. Sustained reserve declines signal net outflow activity into private custody wallets and institutional storage frameworks.
Multi-year exchange reserve compression reflects structural accumulation behavior among long-term holders. Reduced exchange supply limits immediate market liquidity.
Miner Economics Ahead of the 2028 Halving
Network infrastructure data from Blockchain.com recorded 712.45 exahashes per second hash rate on March 12, 2026.
The Bitcoin protocol currently distributes 3.125 BTC per block following the April 2024 halving cycle. The next reward reduction activates in April 2028, lowering block subsidies to 1.5625 BTC.
Mining infrastructure provider Luxor Technology reported on March 14, 2026 that hashprice volatility remains the primary economic constraint for mid-tier mining operators. Mining revenue increasingly depends on transaction fee markets as block rewards decline.
Energy efficiency determines long-term mining margins. Operators with lower power costs maintain operational stability across halving cycles.
Dormant Bitcoin Supply Reduces Market Float
On-chain data from Glassnode shows 15,102,933 BTC classified as illiquid supply as of March 14, 2026.
Glassnode defines illiquid supply as coins held by entities demonstrating accumulation behavior with minimal historical distribution activity.
Additional network metrics indicate 71.9% of all mined Bitcoin has remained inactive for more than 365 days, according to Glassnode data released March 14, 2026.
Blockchain analytics firm Chainalysis estimates 3,790,000 BTC remain permanently inaccessible due to lost private keys.
The effective tradable supply remains significantly lower than the headline circulating supply figure. Exchange reserves and short-term holder balances define the immediate liquidity environment.
Bitcoin Scarcity Compared With Gold
Commodity supply data published March 12, 2026 by the World Gold Council estimates global above-ground gold stocks at 212,582 metric tonnes.
Annual gold mining output adds approximately 3,300 metric tonnes to global supply each year. Bitcoin’s programmed issuance rate now expands supply at a lower annual percentage.
Research released March 13, 2026 by Fidelity Digital Assets states that Bitcoin’s fixed issuance schedule differentiates it from all commodity monetary assets.
Gold supply projections depend on mining output and geological discovery. Bitcoin supply projections derive from deterministic protocol rules embedded within the network.
The remaining issuance trajectory remains fixed: 1,000,000 BTC scheduled for distribution through halving cycles extending toward the year 2140.
