Bitcoin Halving Explained: Why the Four-Year Cycle Still Matters

The Bitcoin halving reduces the reward miners receive for adding a block by 50%, an event hard-coded to occur roughly every 210,000 blocks. By steadily shrinking new supply, it enforces the 21-million cap that underpins Bitcoin’s “digital gold” thesis.

Historically, halvings have preceded major bull markets, though correlation is not causation — liquidity, regulation and adoption all play a role. For investors, the takeaway is structural: supply issuance falls on a known schedule while demand is variable. Understanding that asymmetry matters more than predicting the next all-time high.
