Understanding why all Bitcoins will eventually be mined demands an understanding of what the Bitcoin halving entails. It happens about every four years and is part of the protocol of Bitcoin. Halving is the process whereby only half of the rewards are given to miners for validating transactions and adding them to the blockchain. The most recent halving occurred in May 2020 during which Bitcoin miners witnessed their block reward drop from 12.5 BTC to 6.25 BTC.
The process of generating new Bitcoins and validating transactions within the Bitcoin network is mining. PoW (Proof-of-Work) involves miners using powerful computers to solve complicated mathematical problems. The miner that finds the answer gets permission to connect the chain with another block containing new Bitcoin transactions that are also accompanied by payment for such services.
The miners are responsible for the generation of new Bitcoins, maintaining an orderly and anticipated supply.
Miners contribute to ensuring that transactions remain true, prevented from being spent twice, and the blockchain itself remains intact.
Dispersing authority among a wide pool of miners ensures that the entire Bitcoin network is kept free from the concentration of power in one hand.

As of September 2021, about 18.8 million Bitcoins have already been mined, which means that some 2.2 million are still out there for mining. The speed of new Bitcoin creation reduces with every halving event. This is a purposeful plan that makes mining more difficult and expensive with every increase in Bitcoin supply close to the 21 million ceiling.
In turn, as the mining reward is reduced and demand increases, this will create upward pressure on the price of Bitcoin. Such scarcity may increase making Bitcoin more prestigious as a store of value.
As the Bitcoin reward per block is expected to decrease over time, miners will shift towards transaction fees. Consequently, this may lead to increased cost of charges on Bitcoin transactions.
With this, it can be probable for small and inefficient miners to exit mining as they would not receive any benefit from mining rewards. Such a situation would provide an opportunity for cost-effective mining infrastructure-oriented large players to take control of the mining landscape.
Somewhat, such a quest can also provide an impulse toward the development of relevant technology updates to operate efficiently and sustainably. This may include creating more energy-efficient mining equipment and investigating other consensus algorithms that make Bitcoin's operations more perfect.

Once we reach the 21 million Bitcoin limit, only transaction fees shall make a whole for earning for miners. Such changes are likely to promote greater maturity and stability of the Bitcoin ecosystem. However, this does give rise to questions about the long-term viability and reliability of mining operations and the security of that chain.
Nevertheless, with such challenges emerging, discussions among the members of the Bitcoin community can take place, considering possible changes to protocols, modifications in the mining algorithm, and the creation of other mechanisms for rewarding minors. The result of these conversations will be crucial in shaping the direction that bitcoins take as they go forward, guaranteeing their continued safety and soundness.

Its final mining marks the Bitcoin coinage of 21 million coins, a historical moment in the space of cryptocurrencies. This is what the final destination of the journey that started with Bitcoin was always meant to be. This milestone brings forth certain challenges and uncertainties yet highlights the inherent worth of Bitcoin as a digital repository of value in times when currency uncertainties are growing.
The Bitcoin family is preparing for this significant happening with an open attitude towards adaptability and innovation so that Bitcoin remains a strong and durable financial network in the future. It is not just all about getting there; twenty-one million signifies the continuous growth and transformation of the whole cryptocurrency world.
