The Fourth Bitcoin Halving (2024): What Changed?

By the time Bitcoin’s fourth halving arrived, something had changed that made this reduction event unlike any of the three that came before it: for the first time, regulated spot investment products already existed, giving mainstream investors an easy on-ramp before the halving even happened.

The fourth halving occurred on April 19, 2024, at block height 840,000, cutting the block reward from 6.25 BTC to 3.125 BTC per block — continuing the same mechanical, unchangeable process that had already run three times before, exactly as written into Bitcoin’s code back in 2009.

What made this halving’s context genuinely different was timing relative to a major structural event: spot Bitcoin ETFs had been approved in the United States just a few months earlier, in January 2024, meaning this was the first halving to occur after mainstream, regulated investment vehicles already existed.

Bitcoin traded around $64,000 at the time of the fourth halving — notably, already close to its prior cycle’s all-time high before the halving even occurred, a meaningfully different starting point compared to the previous three halvings, which had all happened while Bitcoin traded well below its prior cycle peak.

This earlier-than-usual price strength led to considerable debate among analysts about whether the traditional halving-then-rally pattern from 2012, 2016, and 2020 would repeat in the same way, given that ETF-driven institutional demand was already actively influencing price before the halving’s supply reduction even took effect.

The fourth halving is widely viewed as a milestone marking Bitcoin’s transition into a more institutionally integrated asset class, with its scheduled supply reduction now interacting with regulated investment flows in a way earlier, more retail-and-miner-dominated cycles never had to account for.
