Bitcoin Cut Miner Pay in Half Again, and the Machines Just Kept Running

On April 19, 2024, Bitcoin's block reward dropped from 6.25 BTC to 3.125. Overnight, miners earned half as much for the same work. No vote, no warning, no exception. The code did what it was written to do in 2009, and the network never blinked.

The April 2024 Bitcoin halving

At block 840,000, on April 19, 2024, Bitcoin did the thing it does roughly every four years: it cut the pay of everyone securing the network in half, automatically, with no appeal. The block reward fell from 6.25 BTC to 3.125 BTC. It was the fourth halving in Bitcoin's history, and the smoothest of them all.\n\nThe mechanism is Satoshi's original design, written into the code before a single Bitcoin was worth anything. Every 210,000 blocks, the reward miners receive for producing a block is cut in half. This is how Bitcoin enforces its 21 million supply cap and its predictable, ever-slowing issuance. The 2024 halving dropped Bitcoin's annual inflation rate from roughly 1.75% to about 0.85% - below gold's, a comparison Bitcoiners never tire of making.\n\nWhat made this halving notable was how ordinary it felt. The first halving in 2012 was an experiment nobody was sure would hold. The 2024 halving happened in a market that had just been reshaped by the January 2024 spot ETF approvals, with BlackRock and Wall Street now holding hundreds of thousands of coins. Bitcoin traded around $64,000 on halving day and would go on to break $100,000 by December and eventually $126,000. The post-halving pattern held a fourth time, though as always, correlation is not proof.\n\nThe real drama was for the miners. Halving your revenue overnight is brutal if you run an industrial mining operation with thin margins and enormous power bills. The 2024 halving accelerated a shakeout: weaker miners capitulated or sold, stronger ones with cheap power and efficient hardware absorbed their market share, and many of the largest operators began pivoting toward AI data centers to diversify away from pure Bitcoin mining. The network's hashrate - the total computing power securing it - barely dipped and then kept climbing to record highs, which tells you the survivors were more than able to fill the gap.\n\nThat is the quiet genius of the halving. It is a scheduled financial shock, announced fifteen years in advance, applied without mercy or exception, and the network simply adapts every time. Miners come and go. The difficulty adjusts. The blocks keep coming every ten minutes. The reward will halve again around April 2028, dropping to 1.5625 BTC, and it will keep halving until the last fraction of a Bitcoin is mined around the year 2140. The machines will keep running.
