Not financial, legal, or tax advice. This explains a protocol mechanism, not a price prediction. Past halvings do not guarantee future results.
The Bitcoin halving is a built-in event, roughly every four years, that cuts the reward miners earn for adding a new block in half, permanently slowing how fast new bitcoin enters circulation. It's the mechanism behind Bitcoin's fixed 21 million supply cap, part of the design covered in \[pillar hyperlink: What Is Bitcoin\].
The mechanism
Every time a miner successfully adds a block, they receive a block reward in newly created bitcoin. The halving simply cuts that reward number in half, permanently, at a predetermined point in the blockchain's history. See How Does Bitcoin Mining Work for how block rewards work day to day.
The schedule
Halvings occur every 210,000 blocks, roughly every four years given Bitcoin's \~10-minute block time. The reward started at 50 BTC per block and has been cut in half multiple times since, stepping down toward zero as the supply cap approaches.
Supply impact
Each halving slows the rate of new bitcoin issuance without warning or a vote. It's automatic and enforced by the code every node runs. Over time, this shrinks new supply growth toward zero, after which miners will earn only transaction fees.
Historical context
Past halvings have coincided with notable market cycles, though correlation isn't the same as causation, and plenty of other factors move price at the same time. Treat the halving as a supply-schedule event, not a guaranteed trading signal.
Stay consistent through the cycle. Rather than trying to trade around halving speculation, Hodl Up supports steady DCA that keeps running regardless of the news cycle.
