Estimating Bitcoin ETF Cost Basis to Map Potential Support Zones

Summary

This analysis estimates the cost basis of holdings across 11 spot Bitcoin ETFs using daily flow records since January 2024 and a FIFO assumption for outflows. It uses the resulting aggregate and price-level distributions to describe how institutional positioning might shape support: the report identifies an aggregate cost basis near $80,000, a concentration around $65,000–$70,000, and relatively sparse accumulation between $75,000 and $85,000. It argues that thinner cost-basis areas could see faster price movement, while profitable holders in denser zones may be more inclined to hold or buy dips.

The analysis also emphasizes that aggregate unrealized gains conceal differences between early and recent buyers, with a substantial share of ETF holdings underwater. These figures and interpretations are a snapshot tied to the report’s writing date and depend on its reconstruction assumptions. FIFO may not capture actual investor-level decisions, and cost basis alone cannot establish that holders will defend a price zone. The document presents structural hypotheses, not a tested price forecast or a complete trading strategy.

Key ideas

• The analysis estimates ETF holdings’ cost basis by applying FIFO to daily flow records across 11 spot Bitcoin ETF issuers.
• It reports an aggregate cost basis near $80,000 and interprets it as a potential psychological threshold for institutional positioning.
• It identifies a concentration of holdings around $65,000–$70,000 and sparse accumulation between $75,000 and $85,000.
• A large underwater cohort coexists with aggregate ETF profits, reflecting different entry prices among investors.
• The proposed support zones are interpretations of a dated snapshot and do not prove that investors will buy or hold at those levels.
