What is a Bitcoin halving

A Bitcoin halving is the moment the reward for adding a block is cut in half. The network aims for a block about every ten minutes. The miner who adds it is paid new coins. After a halving, that payment is half what it was the block before. The coins already in wallets are not cut. Only the new issuance slows.

The cut is on a counter, not on a date a person picks. Bitcoin's software schedules the halving every 210,000 blocks. At ten minutes a block, that is about four years. The clock slips when blocks come faster or slower than the aim, so the calendar date is an estimate until the block arrives. The event itself is the block. The press release is not the mechanism.

Litecoin runs the same idea on a faster clock. Its blocks are aimed at every two and a half minutes, and its supply cap is 84 million, four times bitcoin's 21 million. After the August 2023 halving, the Litecoin reward is 6.25 LTC. The next cut is due in 2027. The chain this desk marked at 15 years is the worked example.

Miners feel it first. Their income in new coins drops by half on that block, while the electricity bill does not. Some miners shut off machines that no longer cover power. Some keep running because the coin's price, or the fees in the block, still pay. The network does not guarantee a miner's profit. It guarantees the reward will be the new, smaller number.

The price is a separate argument, and this page will not settle it. Halvings have landed in very different markets. A cut in new supply can matter if the people who want coins keep buying. It does not force them to buy. A story that says the halving will lift the price is a forecast. The fact is narrower. Fewer new coins will be sold by miners each day, because fewer new coins will exist. Bitcoin's own reward has already been cut several times since 2009, and the coins outstanding kept rising after each one, only more slowly. The next cut will do the same thing: fewer new coins per block, same coins already in wallets.

Fees become a larger share of a miner's pay as the reward shrinks. Users bid those fees for space in the block. A quiet day means a small fee. A crowded day means a large one. The halving does not change the fee market. It changes how much of the miner's income has to come from it. Over enough halvings, the new-coin payment gets small and the fees are what is left.

A halving is also not a stock split and not a burn. A split cuts the price and multiplies the shares so the holder owns the same slice. A burn destroys coins already issued. A halving does neither. The holder of one bitcoin still holds one bitcoin. The next bitcoin, the one that did not exist yet, arrives more slowly.

What comes next on Bitcoin's own calendar is the following halving, on the block count, whenever that block is mined. Litecoin's next one is the 2027 cut already dated in public notes. Until those blocks arrive, the reward stays at the current number. The definition does not wait on the price.
