ビットコイン・暗号資産ETF

デジタル資産を保有するスポット型・先物型ファンド — 利便性がある一方、固有のリスクも伴います。

Spot bitcoin ETFs hold actual bitcoin with a custodian and track its price directly; futures-based crypto funds hold exchange-traded futures contracts instead, which adds roll costs and tracking differences. The spot structure, approved in the U.S. in 2024, removed the need for investors to manage wallets and keys.

These funds inherit crypto's underlying volatility — drawdowns far deeper than equity markets are historical fact — plus fund-specific considerations: custody arrangements, fee levels that vary widely, and reference-price methodology.

The convenience is real (brokerage access, IRAs, no key management), but the wrapper does not change the asset. Position sizing and the issuer's risk disclosures matter more here than in most categories.
