Although the maximum number of Bitcoins is 21 million coins, what has been mined to date does not exceed 19.7 million. The question many people ask is: What prevents the extraction of the remaining coins? The answer lies in the design of the Bitcoin network itself. Its creator, Satoshi Nakamoto, designed a mechanism known as "Halving," which reduces the reward miners receive by half approximately every four years. In this way, the pace of issuing new Bitcoins gradually and deliberately slows down. This mechanism is not random; it aims to limit inflation and ensure the currency's scarcity, making it a store of value akin to gold. According to this system, the last unit of Bitcoins is expected to be mined in 2140. The result? The issuance of Bitcoin is precisely calculated and is one of the main reasons for the appeal of this digital currency and its increasing value over time.
