The mechanics

Bitcoin’s monetary policy is hard-coded: the block reward halves every 210,000 blocks (~4 years). Past schedule:
  • 2009: 50 BTC per block.
  • 2012 halving: 25 BTC.
  • 2016 halving: 12.5 BTC.
  • 2020 halving: 6.25 BTC.
  • 2024 halving: 3.125 BTC.
  • 2028 halving (projected): 1.5625 BTC.

Why markets care


A halving instantly cuts the new BTC entering circulation by 50%. If demand stays constant, basic supply-demand suggests upward pressure on price. Historically the major bull runs (2013, 2017, 2021) post-dated each halving.

What is not automatic

The link is statistical, not mechanical. Macro conditions, ETF flows, miner cost-of-production, and regulatory news can all dwarf the supply story for many quarters. Treat halving as one input, not a guaranteed pump.
