Head and shoulders is a specific Trading coordinate in the Bitcoin knowledge graph. In practical terms, it identifies the subject described here: A three-peak reversal hypothesis whose neckline break and measured target require confirmation rather than assumption. This definition is narrower than promotional usage and should be read together with the implementation, date and evidence attached to the entry.
Head and shoulders is best understood as part of a system rather than as an isolated definition. Its related coordinates show the mechanisms, incentives and historical records that give the term practical meaning.
Head and shoulders describes how participants value, trade or obtain exposure to bitcoin. Market behavior can affect adoption and mining economics, but it does not rewrite consensus rules. Price evidence and protocol evidence answer different questions.
Understanding Head and shoulders helps distinguish a verifiable Bitcoin mechanism or historical record from slogans, products and market narratives.
Primary or authoritative records make these details checkable: the classical top has three peaks with a higher middle head and a neckline through intervening troughs · inverse form mirrors the structure · a neckline break is the usual confirmation event and a measured move is only a projection rule. They should be verified before using the coordinate in analysis.
The practical limit is: three visible swings alone do not confirm the pattern; neckline placement, timeframe and close criteria are analyst choices; confirmation can fail and the target is not a probability estimate. A definition, office, chart pattern or published claim is not by itself a prediction or Bitcoin consensus rule.
