MAXIMUM SUPPLY
The protocol caps the total number of bitcoin at 21 million.
Bitcoin is digital money with a fixed limit. No government, company, or central bank can create more than 21 million. That scarcity is the idea at the center of the entire network—and the reason millions of people believe Bitcoin could become a lasting store of value.
Bitcoin lets people hold and send value without relying on one bank or company to keep the system running. Thousands of independent computers maintain a shared public record called the blockchain.
About every 10 minutes, miners compete to add the next block of transactions. The winning miner proves its work to the network, the block is accepted, and the miner earns newly issued bitcoin plus transaction fees.
Bitcoin’s supply rules are written into the network. New bitcoin enters circulation through mining, but the amount created keeps falling.
The protocol caps the total number of bitcoin at 21 million.
The network targets an average of roughly one new block every 10 minutes.
About every 210,000 blocks—roughly four years—the new-bitcoin reward is cut in half.
Bitcoin began with a block subsidy of 50 BTC. It later fell to 25, then 12.5, 6.25, and now 3.125 BTC per block. That scheduled reduction is known as the halving.
The halving does not guarantee that Bitcoin’s price will rise. It simply makes the issuance schedule increasingly scarce and predictable—something no government-issued currency can promise in the same way.
Investors often compare Bitcoin with gold because both are scarce and are used as stores of value. The comparison is not a prediction—but it shows why Bitcoin attracts so much attention.
If above-ground gold were valued near $22 trillion, 20% would equal about $4.4 trillion. Dividing that by Bitcoin’s 21 million maximum supply produces an illustrative value of roughly $210,000 per bitcoin.
Gold values, Bitcoin supply in circulation, and market prices change. This is a simplified comparison, not a price forecast or financial advice.A 10¹² Mining Co. desktop miner is a real Bitcoin miner. It performs more than one trillion attempts every second as it searches for a valid block.
Its chance of finding a block is extraordinarily small, and no reward is guaranteed. But it turns Bitcoin from something he only reads about into something he can watch, learn from, and participate in from his own desk.
If his solo miner finds the next valid block, the current block subsidy is 3.125 BTC, plus transaction fees, paid to the Bitcoin payout address used in his setup.
