What will happen once all BTC are mined?

Since the genesis block was mined by Satoshi Nakamoto on January 3, 2009, Bitcoin has grown into a billion-dollar industry centered around mining cryptocurrencies. However, with a limited supply of 21 million BTC, the fate of miners after all the coins are issued remains uncertain.
Bitcoin is created through mining, a process involving 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 successfully validate. To date, over 19 million BTC has been awarded to miners as block rewards, leaving around 2 million BTC left to be mined.
Nick Hansen, the founder and CEO of Bitcoin mining firm Luxor Mining, believes that miners will still play an essential role in verifying and recording transactions on the blockchain even after the last BTC is mined. However, their compensation method is likely to shift towards transaction fees becoming the primary incentive.
Currently, successfully validating a new block on the blockchain rewards miners with 6.25 BTC along with transaction fees. Since 2010, fees and block rewards have netted miners over $50 billion. As transaction fees become more critical to Bitcoin mining economics, understanding and forecasting fee dynamics becomes essential.
The last BTC is projected to be mined around the year 2140, based on the block discovery rate and the halving process, which occurs approximately every four years. During halving events, the rewards that miners receive are reduced, creating scarcity and potentially driving up the value of each Bitcoin.
The price of BTC in 2140 will depend on unpredictable factors such as market demand, regulatory environment, technological advancements, and macroeconomic factors. Some experts predict that fiat money systems may have collapsed by then, and Bitcoin could become the global standard unit of account, measured by how much energy a Bitcoin or satoshi can purchase.
While Bitcoin's supply is capped at 21 million BTC according to Satoshi Nakamoto's white paper, the community may decide to extend the hard cap beyond 21 million in the future if they believe the transaction fee incentive is insufficient to keep the network secure.
However, looking at the big picture, Pat White, co-founder and CEO of digital asset platform Bitwave, believes that BTC could fundamentally change over the next century. Quantum computers may have broken the core encryption under Bitcoin by 2140, leading to a major reworking of the protocol.
Regardless of the specific outcomes, the Bitcoin ecosystem is likely to adapt and evolve over time. While the future remains uncertain, solving present-day challenges, such as payments, digital ownership, and banking the unbanked, remains a crucial focus for the crypto community. As the crypto space evolves, innovative solutions will continue to shape the future of Bitcoin and the entire blockchain industry.
