As demand for Bitcoin investment products continues to grow, two important companies have emerged: Grayscale Bitcoin Trust (GBTC) and BlackRock’s iShares Bitcoin Trust.
This tutorial explores the relevance of these investment vehicles and their possible impact on the cryptocurrency market. We also explore the controversy surrounding the technical classification of these trusts and the possibility of the U.S. Securities and Exchange Commission (SEC) approving a spot Bitcoin exchange-traded fund (ETF).
Grayscale Bitcoin Trust’s Dominance
Grayscale Bitcoin Trust has established itself as a top Bitcoin investment vehicle and is now attracting institutional investors seeking exposure to the virtual currency. GBTC shares are currently trading at a significant discount to their net asset value (NAV), raising concerns about the product’s structure and pricing dynamics.
Through Grayscale Bitcoin Trust (GBTC), a well-known investment vehicle offered by Grayscale Investments, investors can gain access to Bitcoin without actually owning Bitcoin. GBTC holds a large number of Bitcoins in trust for the benefit of investors. Since ownership of the underlying Bitcoin holdings is represented by shares issued by the trust, it provides investors with a streamlined and regulated investment vehicle. The public trading of GBTC shares on over-the-counter exchanges provides investors with accessibility and liquidity.

BlackRock's iShares Bitcoin Trust steps in
BlackRock, the world’s largest asset manager, has filed with the SEC to establish a spot Bitcoin ETF under the iShares Bitcoin Trust. Although it is formally a trust, the proposed product will operate like an ETF and provide investors with a controlled and efficient means to track changes in the price of Bitcoin.
The launch of the BlackRock iShares Bitcoin Trust is expected to solve the liquidity problem in the Bitcoin market. BlackRock's involvement will attract huge attention and lead to a large influx of funds into Bitcoin as it is the most prominent asset manager in the world. A large number of new investors seeking price exposure may have an impact on cryptocurrency exchanges as investors may choose to invest in ETFs instead of using exchange direct ownership due to its lower costs.
Disagreement over Bitcoin's actual supply
The growth of “paper bitcoin” — a term for derivative financial instruments that represent bitcoin rather than the actual cryptocurrency — has raised concerns about bitcoin ETFs.
The unlimited possibility of producing paper bitcoins through the derivatives market contrasts with the limited supply of bitcoin. This dynamic could lead to more speculation, affecting the availability of bitcoin and potentially having an impact on the currency’s market price.
Given that the SEC has previously rejected a spot Bitcoin ETF due to concerns about market manipulation, it is unclear whether they will do the same this time.
However, BlackRock’s proposal has more advanced market monitoring capabilities, which could make it the first approved Bitcoin ETF. The ruling could have broad implications for the cryptocurrency market, making it more legitimate and attractive to investors.
The Bitcoin investment space is seeing significant impact from high-profile players like BlackRock’s iShares Bitcoin Trust and Grayscale Bitcoin Trust. Grayscale opened the door for institutional adoption, but BlackRock’s potential approval of its spot Bitcoin ETF could mark the beginning of a new era in cryptocurrency investing.
