Many familiar investment funds operate within the Investment Company Act framework, but not every exchange-traded product does. The SEC's investor bulletin specifically states that spot Bitcoin and ether ETPs described there are not registered investment companies under the 1940 Act. Their offerings and securities are instead registered under the applicable Securities Act and Exchange Act requirements. Calling them ETFs colloquially should not erase this difference in their legal structure and protections.

A spot crypto commodity-trust product generally provides exposure through shares linked to assets held by the vehicle. That differs from personally holding the underlying coin and from owning a fund that obtains exposure using futures or other instruments. The prospectus describes custody, valuation, fees, creation and redemption, and other operational arrangements. A familiar stock-exchange ticker does not establish that the product has the same rules as a broad-market mutual fund.

Registration and exchange-listing approval are not endorsements of the underlying asset's value or a guarantee against losses. Compare the exact product's legal form and filings rather than applying one statement to every vehicle with Bitcoin in its name. Futures funds and commodity trusts can sit within different regulatory structures while both offering price exposure. An encyclopedia should name the applicable framework precisely and avoid implying that protections associated with 1940 Act funds automatically accompany every spot crypto ETP.
