Bitcoin’s design includes a hard cap of 21 million coins. This scarcity is a key element of its value proposition. But what occurs when the last Bitcoin is mined? This event is projected to happen around the year 2140;

Transaction Fees Become Primary Incentive
Currently‚ miners are rewarded with newly minted Bitcoins (block subsidy) and transaction fees. Once all 21 million are mined‚ the block subsidy will disappear. Miners will then rely solely on transaction fees for revenue. If bitcoin price doesnt rise enough‚ then the miners may decide to stop mining‚ as 0.00001 BTC might not be worth it. If no one does anymore mining‚ then transactions will go unprocessed for now and the bid price for mining would rise.
Impact on Bitcoin’s Value
By limiting the supply of bitcoins‚ the value of each individual Bitcoin is theoretically increased. This is because as demand for Bitcoin increases but the supply remains fixed‚ the price of Bitcoin is likely to increase as well.
Potential Challenges and Considerations
Security Concerns: If transaction fees are insufficient to incentivize mining‚ the network’s security could be compromised.
Fee Market Dynamics: Users may need to pay higher fees to ensure their transactions are processed promptly.
Software Updates: The 21 million supply of the original bitcoin can never be changed. Bitcoin critics claim that Bitcoins rules can be easily changed by altering Bitcoins source code. However‚ Bitcoin is governed by the software run by nodes‚ not by the source code. Removing the strict limit on the number of bitcoin would destroy the value of Bitcoin as a system and alienate investors and long-time believers
