About

BTC Exposure is a free, open-source dashboard for tracking your total Bitcoin exposure across the instruments that actually matter to BTC-thesis investors:

• Direct BTC (custody you control)
• MSTR equity — the largest corporate Bitcoin holder
• Spot BTC ETFs — FBTC (Fidelity), IBIT (iShares), ARKB (ARK 21Shares), BITB (Bitwise)
• Strategy preferreds — STRK (Strike — 8% convertible) and STRC (Stretch — 9% perpetual)

What it computes

• mNAV (simple and full / EV) — premium or discount to BTC NAV
• BTC per share / sats per share — Saylor's accretion KPI for MSTR
• Implied $/BTC via MSTR — effective BTC price you're paying through MSTR
• BTC torque — leverage of MSTR vs spot BTC
• Effective BTC exposure — total BTC equivalent across direct + MSTR + ETFs + STRK
• Price projections — Power Law (Santostasi), ARK Big Ideas 2030, Bitwise LTCM 2025, VanEck 2050
• Halving cycle overlay — current cycle vs prior halvings (2012, 2016, 2020)
• Top BTC holders — public corporates and all entities, trailing 12 months
