Overview​

Entity Cost Basis represents the total USD amount a specific entity has spent acquiring its Bitcoin holdings. This is the aggregate investment — the sum of all purchase transactions at their historical prices.

Unlike Realized Price (per-BTC average), Cost Basis shows the total capital deployed into Bitcoin by the entity.

Interpretation​

  • Rising Cost Basis with stable holdings: Entity is not buying more, but cost basis remains the historical total spent.
  • Rising Cost Basis with rising holdings: Entity actively accumulating — spending more capital on BTC.
  • Cost Basis vs Market Value: If total current value (holdings × spot price) exceeds cost basis, the entity has unrealized profit. If below, unrealized loss.

For Strategy (formerly MicroStrategy), cost basis exceeds $57 billion — the largest corporate Bitcoin investment in history.

Use Cases​

  • Total investment tracking: How much capital has the entity deployed into Bitcoin?
  • ROI calculation: Compare cost basis to current market value (holdings × spot price)
  • Scale comparison: Which entities have invested the most in absolute terms?
  • Capital allocation analysis: Track how aggressively an entity is deploying capital into BTC over time
