Margin is a specific Trading coordinate in the Bitcoin knowledge graph. In practical terms, it identifies the subject described here: Collateral posted to support a leveraged position, governed by initial and maintenance requirements. This definition is narrower than promotional usage and should be read together with the implementation, date and evidence attached to the entry.
Margin 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.
Margin 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 Margin helps distinguish a verifiable Bitcoin mechanism or historical record from slogans, products and market narratives.
Primary or authoritative records make these details checkable: margin is borrowed purchasing power secured by account assets · account equity equals market value minus the margin loan · initial, maintenance and broker house requirements can differ, while interest and forced liquidation alter outcomes. They should be verified before using the coordinate in analysis.
The practical limit is: leverage magnifies losses as well as gains; a broker may raise house requirements and liquidate without waiting for the client's preferred timing; exchange margin for derivatives is not identical to a securities margin loan. A definition, office, chart pattern or published claim is not by itself a prediction or Bitcoin consensus rule.
