Strike is a specific Adoption coordinate in the Bitcoin knowledge graph. In practical terms, it identifies the subject described here: A Bitcoin and Lightning app for buying, selling, sending and receiving Bitcoin; country availability and product terms vary. This definition is narrower than promotional usage and should be read together with the implementation, date and evidence attached to the entry.
Strike 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.
Strike belongs to the documented history and social layer around Bitcoin. Primary records can establish what was published, built or decided; motives, influence and later interpretation should remain separate from those verifiable facts.
Understanding Strike helps distinguish a verifiable Bitcoin mechanism or historical record from slogans, products and market narratives.
Primary or authoritative records make these details checkable: Strike is a payments and Bitcoin service using Lightning and other rails for supported customers; current buying, custody, withdrawal, remittance and fiat features vary by country and contracting entity. They should be verified before using the coordinate in analysis.
The practical limit is: a Lightning-enabled interface does not mean every transfer settles over Lightning, is self-custodial or avoids currency conversion; spreads, custody, limits, compliance, availability and legal terms matter. A definition, office, chart pattern or published claim is not by itself a prediction or Bitcoin consensus rule.
For the clearest picture, read this entry together with Lightning Network, Lightning Address, Dollar-cost averaging (DCA), Bitcoin, Bull Bitcoin, Remittances. The reverse links also lead from Bull Bitcoin, Boltz.
