The Core Warning: Bitcoin Scarcity Worse Than Thought
Blackrock, the world's largest asset manager, published a report on February 26 authored by Brett Wager and Michael Gates, highlighting Bitcoin's potential role in investment portfolios. The report emphasized Bitcoin's ability to enhance diversification, stating: “As multi-asset portfolio constructors, we believe bitcoin has long-term investment merit for certain investors and can potentially provide unique and additive sources of diversification to portfolios.”
The authors pointed to geopolitical instability, rising sovereign debt, and excessive government spending as factors that could further drive interest in BTC. They also noted that regulatory shifts could remove barriers to innovation: “A more bitcoin-friendly administration could ease regulatory bottlenecks, potentially unlocking a wave of pent-up innovation and infrastructural development.”
Supply Reality: Far Less Than 21 Million
The report highlighted the impact of Bitcoin exchange-traded products (ETPs), which launched in 2024 and have since seen substantial inflows. According to Blackrock, broader institutional participation could stabilize Bitcoin’s historically volatile price movements. The authors underscored the cryptocurrency’s scarcity, explaining that its real circulating supply is lower than its theoretical 21 million cap.
“Less widely known is that the real available float is likely far smaller, with a conservative estimate of 3 to 4 million issued bitcoins visible on the blockchain but considered permanently inaccessible (and therefore out of circulation) due to lost, forgotten, or otherwise destroyed keys,” they wrote. The report then illustrated the severity: “To illustrate how few available bitcoins there are, if every millionaire in the U.S. asked their financial advisor to get them 1 bitcoin, there wouldn’t be enough.” According to recent estimates, the United States has approximately 22 million millionaires, while the maximum possible Bitcoin supply is 21 million, with millions already lost permanently.
Defending Bitcoin’s Intrinsic Value
Addressing skepticism about Bitcoin’s intrinsic value, Blackrock pushed back against critics who claim the cryptocurrency lacks fundamental worth. “Critics’ go-to refrain is bitcoin has no intrinsic value. To the contrary, in our view, the discussed embedded characteristics represent fundamentally real and attractive sources of intrinsic value, which we expect will be recognized by more people in more places over time – particularly in a debt-laden, digital-first, and increasingly AI-entrenched world.” The report framed Bitcoin as a resilient asset with a fixed supply, decentralized infrastructure, and growing institutional adoption, making it an increasingly relevant investment option in today’s evolving financial landscape.
The warning from Blackrock — the manager of over $10 trillion in assets — carries significant weight in the financial industry. It signals that even traditional finance giants are taking Bitcoin's supply constraints seriously, potentially accelerating adoption among institutional investors seeking exposure to a scarce digital asset with no central authority.
