What the halving is
Every 210,000 blocks, roughly every four years, the new bitcoin paid to miners per block is cut in half. It started at 50 BTC in 2009; since April 2024 it is 3.125 BTC. The cap of 21 million coins comes from this schedule.
The power law does not use halvings. Its trend is one smooth curve fitted to the price against Bitcoin's age. The four-year cycles show up as swings around that curve: deep under it before or near each halving, far above it a year or so later.
The swings are shrinking. A year after the 2012 halving the price was about 80 times higher; after 2024, about 1.3 times. Each cycle peaked lower against the trend than the one before. Nothing guarantees the pattern repeats in 2028.
