When Will Bitcoin Mining End

Timeline for Bitcoin Mining Conclusion

Bitcoin mining is projected to conclude in the year 2140, when the total supply of Bitcoin reaches its maximum limit of 21 million coins. At that point, miners will no longer receive newly minted block rewards and will instead rely on transaction fees as their primary source of income. This predetermined endpoint is a fundamental feature of Bitcoin's design, ensuring a fixed and predictable monetary supply that distinguishes it from traditional fiat currencies.

Current Bitcoin Supply Status

In recent years, the Bitcoin network has seen significant growth in adoption and mining activity. The vast majority of Bitcoin's total supply has already been generated, with less than 3 million bitcoins remaining to be mined. The mining process itself involves verifying and confirming transactions across the Bitcoin network, with miners receiving compensation in the form of newly created coins and transaction fees for their computational work and contribution to network security.

Post-Mining Network Security

Following the conclusion of Bitcoin mining in 2140, miners will continue to play a critical role in maintaining network integrity. They will continue to verify transactions and earn transaction fees as their primary income source, ensuring the ongoing security and functionality of the Bitcoin network. This transition from block rewards to transaction fee-based compensation represents a sustainable long-term model for maintaining network security without relying on the perpetual creation of new bitcoins. The fee-based incentive structure ensures that miners remain motivated to secure the network for generations to come.

FAQ

When will Bitcoin mining completely end?

Bitcoin mining will completely end around 2140, when all 21 million bitcoins have been mined. After that, no new bitcoins will be issued, and miners will only earn transaction fees from the network.

Why will Bitcoin mining stop? What is the mechanism of block reward halving?

Bitcoin mining stops because block rewards halve every four years, eventually reaching zero. This mechanism ensures Bitcoin's limited supply of 21 million coins, making it deflationary and scarce by design.

After Bitcoin mining ends, how will miners earn revenue?

Miners will earn revenue from transaction fees. While miners currently receive block rewards that halve every four years, once all Bitcoin are mined, transaction fees will become their primary income source, incentivizing them to continue validating and securing the network.

What impact will Bitcoin mining ending have on price and network security?

Bitcoin mining completion may cause price volatility driven by supply-demand dynamics. Network security remains robust through distributed validation and transaction fees replacing block rewards, ensuring long-term stability.

How many bitcoins are left to be mined?

As of January 2026, approximately 19.44 million bitcoins have been mined out of the 21 million total supply. This means around 1.56 million bitcoins remain to be mined, with the last bitcoin expected to be mined in 2140.

Will the Bitcoin network continue to operate after mining ends?

Yes, the Bitcoin network will continue operating after mining ends. It will keep validating transactions and maintaining the blockchain through alternative incentive mechanisms like transaction fees, ensuring long-term network functionality and security.
