Bitcoin Halving — Why It Matters for Prices
Every ~4 years Bitcoin halves the new supply issued to miners. What the halving is, why it has historically preceded rallies, and why it guarantees nothing.
What the halving is
Roughly every 210,000 blocks (about four years), Bitcoin's block reward is cut in half, so miners receive fewer new BTC:
- 2012: 50 → 25 BTC/block
- 2016: 25 → 12.5 BTC/block
- 2020: 12.5 → 6.25 BTC/block
- 2024: 6.25 → 3.125 BTC/block
- 2028 (expected): 3.125 → 1.5625 BTC/block
Why it can affect price
The logic is simple supply and demand: fewer new coins are created each day while demand stays the same or grows, which reduces selling pressure from freshly mined supply.
Note the timing, though — price has historically not reacted the day of the halving. Any move has usually played out over the following 6–12 months.
Historical context
Past cycles saw large gains in the year after each halving, with the size of the move shrinking each time (from roughly 100x after 2012 down to single-digit multiples in later cycles). The 2024 cycle was further complicated by spot Bitcoin ETFs. Past performance is not a promise of future results.
The halving is not a guarantee
A halving plus a healthy market has tended to be bullish. A halving during a poor macro backdrop (rate shocks, risk-off sentiment) can still see prices fall. Treat the halving as one factor among many, not a signal to bet the farm.
Pairing it with DCA
Some long-term investors simply lean on DCA around these events — buying steadily before and after the halving rather than trying to time the exact turn. That keeps a single narrative from driving oversized decisions.
