what's ishares bitcoin trust?
The iShares Bitcoin Trust is a spot Bitcoin exchange-traded fund (ETF) launched by BlackRock, one of the world's largest asset managers, under its iShares brand. It provides investors with indirect exposure to Bitcoin by holding actual Bitcoin in custody, aiming to track the performance of Bitcoin's spot price minus fees and expenses. The ETF trades on major U.S. stock exchanges, allowing traditional investors to gain access to Bitcoin through familiar brokerage accounts without needing to manage cryptocurrency wallets or exchanges directly. Unlike futures-based Bitcoin funds, the iShares Bitcoin Trust directly purchases and stores Bitcoin through regulated custodians, ensuring security and compliance with U.S. securities regulations. It is not registered as an investment company under the Investment Company Act of 1940, operating instead as a trust that issues shares backed by Bitcoin holdings. Investors buy shares of the trust, which represent a fractional ownership of the underlying Bitcoin reserves. The product democratizes Bitcoin investment by integrating it into conventional portfolios, subject to the same regulatory oversight as other ETFs. It appeals to institutional and retail investors seeking Bitcoin exposure without the complexities of direct crypto ownership, while BlackRock handles custody, trading, and reporting to maintain transparency and liquidity.
