The bull case for bitcoin
Proponents argue bitcoin could become a widely adopted digital store of value, like a digital gold. They point to:
- Bitcoin’s scarcity and decentralization. Supply is capped at 21 million coins, a feature hard-coded into bitcoin’s protocol.2 Scarcity is the foundation of the “bitcoin as digital gold” narrative, the idea that it’s an alternative to fiat currencies whose values are being systemically eroded by an explosion in government debt levels. The decentralized nature of bitcoin’s supply means no single entity can alter its issuance, further distinguishing it from traditional monetary systems.
- The great wealth transfer. As Millennials (born 1981–96) and Gen Z (born 1997–2012) inherit over $100 trillion in assets,3 their investing preferences will shape future markets. Men aged 18–49, the most receptive (25% in surveys owned bitcoin4), and others in these generations, seem poised to drive broader cryptocurrency adoption.
- Improving regulatory clarity around the world. New legislation and frameworks introduced in the United States and abroad are reducing uncertainty, legitimizing bitcoin among both institutions and individuals, and encouraging broader participation in the market.
- Maturing infrastructure. U.S. spot bitcoin ETFs, launched in 2024, have attracted $62 billion in net inflows,5 signaling strong investor interest. The growth of bitcoin derivatives markets, lending platforms and secure custody solutions further supports mainstream adoption.
- Growing institutional acceptance. Major financial institutions are beginning to recommend bitcoin allocations in client portfolios. Even small allocations by large asset managers could significantly increase demand.
- Global accessibility and portability. Bitcoin operates without a central authority, generally making it accessible to anyone anywhere with an internet connection. Its borderless and digital nature allows for easy transfer and storage, making it far more portable than a physical asset such as gold. This portability is especially attractive in those emerging markets with unstable currencies.
Bitcoin’s market capitalization, just below $2 trillion, is large for a single security (it’s roughly the market cap of Meta). To be sure, it’s small compared to traditional asset classes—$2 trillion is just 6% of gold’s total market cap. We caution against drawing direct parallels, given their still distinct features, but bitcoin bulls commonly speculate that if bitcoin’s market cap were ever to match gold’s, a coin would theoretically be worth more than $1.5 million—about 20 times higher than today.
This combination of scarcity, growing mainstream acceptance and decentralization underpins the optimistic outlook for bitcoin’s long-term value.
Indeed, while the bull case is compelling, we note several risks and uncertainties that must be weighed carefully before considering any allocation.
Despite real progress, regulation remains fragmented
One reason why we don’t think bitcoin is ready for core portfolios is the regulatory landscape. In 2025, most economies signaled an opening toward the digital assets ecosystem,6 which supported bitcoin’s entry into institutional finance. But the environment is fragmented overall.
Policy progress or regression lies in policymakers’ hands, and while the lack of global regulatory consistency is inherent in decentralized assets, it leaves investors without the protections and stability that oversight is intended to provide. Although bitcoin is generally further along its regulatory journey than other parts of the ecosystem, its acceptance has been bolstered by advancements in digital asset regulation as a whole.
Striking a balance between regulations that foster investor confidence and cryptocurrencies’ original, decentralized purpose will likely remain a key challenge for the industry.
Swings are tempering, but bitcoin remains volatile
Bitcoin is notorious for its volatility. Over the past decade, bitcoin has been four times more volatile than global equities—nearly 70%, versus global equities’ 16%. Bitcoin has also seen 14 bear markets (meaning a decline of 20% or more) over the same period; global equities had two. And bitcoin’s declines have been worse: The average loss, during bitcoin’s five worst declines, was 57%. For global equities, the five worst slumps averaged to a 21% decline.
However, because bitcoin is a relatively new asset, the period used for analysis matters. Recently, bitcoin’s volatility has been easing. Since the SEC approved the first bitcoin spot ETFs in January 2024, the cryptocurrency’s annualized volatility has been about 45%, much lower than that of the prior decade.
