Bitcoin Halving
In short
Every ~4 years, Bitcoin miner rewards are cut in half — historically bullish
Every ~4 years, the reward for mining new Bitcoin is cut in half. This reduces the supply of new Bitcoin entering the market. Historically, each halving has preceded a major Bitcoin bull run within 12-18 months.
Bitcoin halving occurs approximately every 210,000 blocks (~4 years). It reduces the block subsidy (miner reward) by 50%. With fixed demand and reduced supply, halvings have historically been bullish catalysts. The next halving will reduce rewards from 3.125 BTC to 1.5625 BTC per block.
Formula
New BTC supply after halving = 6.25 → 3.125 → 1.5625 BTC per blockRelated concepts
- Bitcoin Dominance — Bitcoin dominance shows how much of all crypto money is in Bitcoin. High dominance (>60%) means investors prefer Bitcoin's safety. Falling dominance during a bull market often signals altcoin season — smaller coins outperforming Bitcoin.
- Crypto Market Cap — Crypto market cap = price × number of coins in circulation. Bitcoin at $60,000 with 19.5M coins = ~$1.17T market cap. A rising total crypto market cap means money is flowing into the space.
- On-Chain Metrics — Unlike stocks, crypto blockchains are public. You can see exactly how many coins are moving, who holds what, and how network activity is changing. When on-chain activity rises before price, it can signal upcoming moves.
