In the Spotlight: BlackRock’s iShares Bitcoin Trust (IBIT)
In just 21 months of existence, BlackRock’s iShares Bitcoin Trust (IBIT) has carved a remarkable niche as the fastest-growing product in the company’s history, surpassing nearly all of its other exchange-traded funds (ETFs). With nearly $100 billion in assets and generating approximately $245 million in annual fee income, IBIT stands as a testament to the shifting landscape of asset management—especially in the realm of cryptocurrencies.
IBIT: From Bold Experiment to Flagship Product
Launched less than two years ago, IBIT has transitioned from a speculative investment to a cornerstone of the iShares lineup. Currently, it boasts about $93.5 billion in assets under management, which corresponds to roughly 760,000 Bitcoin (BTC), capturing nearly 60% of the US spot Bitcoin ETF market. The fund operates with a management fee of 0.25%, resulting in an impressive annual revenue of around $244.5 million.
To put its success into perspective, consider that Vanguard’s S&P 500 ETF (VOO) took over five years—specifically 2,011 days—to reach the coveted $100 billion milestone. In contrast, IBIT is approaching this benchmark in a mere 435 days, demonstrating the robust demand for regulated Bitcoin exposure among both institutional investors and mainstream audiences. High-profile endorsements, such as a $116 million stake from Harvard University’s endowment fund, serve as additional validation of Bitcoin’s maturing status as an asset class.

BlackRock’s Crypto Strategy: Version 2.0
Emboldened by the success of IBIT, BlackRock is already planning its next venture with the creation of a trust in Delaware for a new product named the "Bitcoin Premium Income ETF." This innovative offering aims to generate regular income by selling covered calls on Bitcoin futures, cleverly capitalizing on market volatility while offering investors a portion of the upside potential.
According to Bloomberg, the roadmap for BlackRock remains firmly focused on Bitcoin and Ether, purposefully bypassing a rush to include altcoins—perhaps indicating a measured approach to the burgeoning crypto market.
Distinguishing Between Self-Custody and Delegation
It’s crucial to note that an ETF like IBIT provides price exposure but does not confer the same rights and protections as self-held Bitcoin. With IBIT, investors gain access to Bitcoin’s price movements without actual ownership, leading to the question of how individuals should manage their cryptocurrency holdings.
Self-Custody: Control with Responsibility
Self-custody involves holding your Bitcoin directly, empowered by private keys—a string of words known as a seed phrase or “recovery phrase.” Possessing this phrase confirms ownership on the network. However, losing or disclosing it means irreversible loss or theft. Many users opt for hardware wallets for added security, and some even use multisignature setups, which require multiple keys for transactions.
Advantages of self-custody:
- Total sovereignty: No one can freeze or censor your transactions.
- Security control: You manage your funds and are responsible for your security protocols.
However, self-custody comes with its own challenges, such as the need for meticulous backup practices and the stress of being completely reliant on your personal security measures.
Delegation: Convenience with Risks
In contrast, delegating custody means relying on a third party—be it an exchange or an ETF like IBIT. This method removes the burden of security management and simplifies the investment process but introduces its own set of risks, such as potential hacking, bankruptcy, or operational failures.
Here’s what to consider with delegation:
- Ease of access: Quick trades and user-friendly interfaces.
- Lack of ownership: You don’t own on-chain Bitcoin and miss out on technical advantages like forks or governance opportunities.
Balancing Convenience, Cost, and Control
Ultimately, the decision between self-custody and delegation hinges on an individual’s unique needs and preferences. Many investors find a balanced approach works best—keeping a long-term self-custody strategy for security while using delegated services for liquidity and day-to-day transactions.
In this evolving landscape, awareness and understanding of both strategies are essential for navigating the complexities of investing in Bitcoin and broader cryptocurrency markets. Whether through IBIT or directly holding Bitcoin, the choices investors make today will shape their experiences in this dynamic, often unpredictable, financial ecosystem.
