Bitcoin mining at 93% with 7% left until 2140.
Halving cuts block rewards every 210,000 blocks. Circulating supply hits 20,343,750 BTC in 2024. Final Bitcoin issuance expected by 2140 at block 6,930,000.Scarcity drives Bitcoin’s value as rewards shrink over time.
#BitcoinMining #BitcoinHalving #Cryptocurrency #Blockchain #BTC Bitcoin mining has reached a critical milestone. Data shows 93% of all Bitcoin has been mined as of May 2025. The final issuance is projected to occur by 2140.
A timeline shared on X highlights the Bitcoin halving schedule. It details block rewards, circulating supply, and percentage of total supply mined over the years. The chart, sourced from CoinBeast, spans from 2009 to 2140.
In 2009, the block reward started at 50 BTC. The circulating supply was 10,500,000 BTC, representing 50% of the total supply. By 2012, at block 210,000, the reward halved to 25 BTC. The circulating supply rose to 15,750,000 BTC, or 75% of the total.
The halving continued every four years. In 2024, at block 840,000, the reward dropped to 3.125 BTC. The circulating supply reached 20,343,750 BTC, equating to 93.78% of the total supply. By 2032, at block 1,260,000, the reward will be 1.5625 BTC, with 98.4375% of Bitcoin mined.
The chart projects that by 2140, at block 6,930,000, the reward will be 0.00000001 BTC. The circulating supply will hit 20,999,999.9769 BTC, marking 100% of the total supply.
Separately, a report confirms that 93% of Bitcoin’s total supply is already in circulation. The remaining 7% will be mined over the next 115 years. The process will conclude in 2140, when the last Bitcoin is issued.
Halving Impact on Bitcoin Supply
Halvings reduce the rate of new Bitcoin entering circulation. The 2024 halving cut the block reward from 6.25 BTC to 3.125 BTC. This event, occurring at block 840,000, slowed the issuance of new coins. The circulating supply stood at 20,343,750 BTC, or 93.78% of the total 21 million BTC cap.
Future halvings will further decrease rewards. By 2040, at block 1,680,000, the reward will be 0.1953125 BTC. The circulating supply will reach 20,958,984.375 BTC, or 99.60937511% of the total. This gradual reduction ensures Bitcoin’s scarcity, a core feature of its design.
The halving mechanism, coded into Bitcoin’s protocol, occurs every 210,000 blocks. It aims to control inflation and maintain value over time. By 2140, the block reward will be nearly zero, halting new Bitcoin issuance.
Long-Term Outlook for Bitcoin Mining
Bitcoin’s mining timeline stretches over a century. In 2060, at block 2,520,000, the block reward will be 0.01953125 BTC. The circulating supply will be 20,994,873.0463 BTC, or 99.951171985% of the total. The issuance rate will continue to shrink with each halving.
By 2100, at block 5,040,000, the reward will drop to 0.000152587890625 BTC. The circulating supply will be 20,999,989.735 BTC, or 99.99998408% of the total. The final issuance in 2140 will mark the end of Bitcoin mining.
Bitcoin’s fixed supply of 21 million coins sets it apart from traditional currencies. The slow issuance of the remaining 7% over the next 115 years reinforces its scarcity. Miners will rely on transaction fees as block rewards diminish.
