Support and resistance is a specific Trading coordinate in the Bitcoin knowledge graph. In practical terms, it identifies the subject described here: Price zones where prior trading has repeatedly attracted demand, supply or attention. This definition is narrower than promotional usage and should be read together with the implementation, date and evidence attached to the entry.
Support and resistance 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.
Support and resistance 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 Support and resistance helps distinguish a verifiable Bitcoin mechanism or historical record from slogans, products and market narratives.
Primary or authoritative records make these details checkable: support and resistance label price regions where prior trading or predefined rules suggest changed order response; reproducible use requires exact level construction, tolerance, confirmation and invalidation. They should be verified before using the coordinate in analysis.
The practical limit is: a line on a chart is not a physical barrier or guaranteed reversal, and levels selected after the event invite hindsight; liquidity, regime, fees, false breaks and multiple testing matter. A definition, office, chart pattern or published claim is not by itself a prediction or Bitcoin consensus rule.
