What It Is

Regulated Exposure: Trades like any ETF; held in brokerage accounts.
Real BTC Custody: Qualified custodians store BTC in segregated cold storage with audits and insurance clarity.
Transparent Operations: Issuers publish methodology, holdings, and policies.

Why It Matters

Access: Simplifies crypto allocation for retail, advisors, and institutions.
Liquidity: Market-maker competition tightens spreads and improves execution quality.
Governance: Elevates custody and disclosure standards across the ecosystem.

Core Mechanics

Secondary Market: Investors trade ETF shares; market makers quote bids/asks.
Premium/Discount: APs create/redeem shares when ETF diverges from NAV, aligning price with spot.
In-Kind vs Cash: APs deliver BTC (in-kind) or cash (issuer buys BTC). See How ETF Issuers Buy and Store Bitcoin.

Custody Architecture

Cold Storage Dominance: Minimal hot wallet use; multi-sig; role separation.
Audits and Attestations: Independent verification of holdings and controls.
Insurance Scope: Defined coverage for custody-related risks. For custody evaluation checklists, read How Spot Bitcoin ETFs Hold Real BTC.
