Future of Bitcoin after all BTC are mined
The Future of Mining in the Blockchain Industry
The blockchain industry, which was initiated by Satoshi Nakamoto with the mining of the genesis block on January 3, 2009, has grown into a billion-dollar industry centered around mining cryptocurrencies. However, with a capped supply of Bitcoin (BTC) at 21 million, the future of miners after the last coins are issued is uncertain.
Bitcoin is created through the process of mining, which involves using computer hardware to solve complex mathematical problems and verify transactions on the blockchain network. Miners are rewarded with a predetermined amount of BTC for each block of transactions they validate. According to the Blockchain Council, over 19 million BTC has been awarded to miners in block rewards, leaving only a limited supply available.
Once the cap of 21 million BTC is reached, miners will no longer receive rewards for verifying transactions. However, this does not mean that their role in the blockchain ecosystem will become obsolete. Nick Hansen, the founder and CEO of Bitcoin mining firm Luxor Mining, explains that while the loss of block rewards will change the way miners are compensated, they will still play an essential role in verifying and recording transactions on the blockchain.
Currently, miners are rewarded with 6.25 BTC, worth around $188,381, for successfully validating a new block on the blockchain. In addition to block rewards, miners also receive transaction fees. According to data from on-chain analytics firm Glassnode, miners have earned over $50 billion from fees and block rewards since 2010.
Hansen believes that transaction fees will eventually become the primary incentive for miners to continue their operations even after all BTC is mined. As transaction fees increase in importance, understanding fee dynamics and forecasting them into the future becomes crucial. Hansen points out that transaction fee dynamics can be analyzed using tools like Bitcoin Ordinals.

However, this shift towards transaction fees as the main source of miner compensation is still expected to take years. Based on the block discovery rate and the halving process, the last BTC is projected to be mined around 2140. A Bitcoin halving, which reduces the rewards for miners, is scheduled to occur roughly every four years. The next halving is predicted to take place around April 2024, reducing the reward for each block to 3.125 BTC.
The limited supply of BTC is expected to create scarcity, potentially driving up its value as demand increases. However, the price of BTC in 2140 will depend on various factors such as market demand, regulatory environment, technological advancements, and macroeconomic factors. The scarcity created by all BTC being in circulation does not guarantee price increases; it is subject to market dynamics.
As the mining landscape evolves, Jaran Mellerud, a research analyst from Hashrate Index, predicts that transaction fees will drastically increase and become the primary source of revenue for mining firms. The block subsidy, which will have already become minuscule by the time the last BTC is issued, will not significantly impact the coin supply.
Mellerud speculates that by the time the last BTC is mined, fiat money systems may have collapsed, and Bitcoin could become the standard unit of account globally. Under such circumstances, measuring the purchasing power of Bitcoin would be based on how much energy a Bitcoin or satoshi can purchase, similar to how the purchasing power of the US dollar is measured in terms of energy.
While miners will remain critical to the blockchain ecosystem, it is anticipated that not all miners will survive in the face of mounting costs. Glassnode data shows that miners have already experienced long periods of unprofitability since 2010. Some miners may shut down, and manipulation techniques may be employed to drive up fees. However, these scenarios are likely to unfold before the last Bitcoin is mined.
Looking towards the future, Pat White, co-founder and CEO of Bitwave, believes that BTC could undergo fundamental changes over the next century. White suggests that by 2140, quantum computers may have broken the core encryption of Bitcoin. This would necessitate a major reworking of Bitcoin’s encryption layer and upward, allowing the developer community to assess whether additional mining or a transaction fee-based network is required for security.
White further speculates that the BTC hard cap of 21 million could be extended if the community believes the transaction fee incentive is insufficient to maintain network security. However, the impact of such a change on the price of BTC remains unclear. White believes that the price of Bitcoin will stabilize at a global inflation-reflecting price point. The major price movement may occur if one or more nations adopt Bitcoin as their reserve currency.
In conclusion, the future of mining in the blockchain industry is not limited to the issuance of the last BTC. Miners will continue to play a crucial role in verifying and recording transactions on the blockchain. While the compensation structure may evolve towards transaction fees, the landscape will take time to shift. The scarcity created by a capped supply may drive up the value of BTC, but market dynamics will ultimately determine its price. As the industry progresses, it is important to address current challenges and focus on solving problems related to payments, digital ownership, and financial inclusion.
