Bitcoin is moving deeper into conventional finance as advisers, brokerage accounts, and retirement frameworks widen the pool of potential owners without requiring crypto-native infrastructure. Grayscale argues that a future buyer may encounter Bitcoin through an existing portfolio: an adviser can add a small allocation, a brokerage can hold a spot ETF, and future retirement products could place Bitcoin inside familiar investment wrappers.
According to the 2026 Bitwise and VettaFi adviser survey, 42% of advisers could purchase crypto in client accounts, up from 35% in 2024 and 19% in 2023. In 2025, 32% of advisers invested client money in crypto, up from 22% a year earlier, and 64% of crypto-using advisers reported client allocations above 2%, compared with 51% in the previous survey. This suggests access is turning into actual usage and allocations are becoming less symbolic.
Spot Bitcoin exchange-traded products accelerated the process after the SEC approved their listing and trading in January 2024. Fidelity's 2026 'Getting Off Zero' research says money managers should have a well-informed rationale for maintaining a zero Bitcoin allocation, while noting zero can suit investors with mandates or volatility limits. That framing places Bitcoin inside the investment committee process before any allocation occurs.
Grayscale also ties adoption to broader blockchain finance. Federal Reserve researchers said stablecoin market capitalization expanded by about 50% in 2025 and reached $317 billion by April 6. The SEC defined tokenized securities as financial instruments represented by crypto assets with ownership recorded on crypto networks. Stablecoins and tokenization create an indirect route toward Bitcoin familiarity as banks, brokers, asset managers, and payment companies gain operational experience in custody, settlement, and crypto networks.
The retirement market could extend distribution further. The Department of Labor proposed a rule on March 30 covering how 401(k) fiduciaries evaluate alternative assets, potentially affecting retirement options for more than 90 million Americans. ICI reported $13.8 trillion in employer-based defined-contribution plans at the end of the first quarter of 2026, with $9.9 trillion in 401(k) plans. A 1% allocation across 401(k) assets would equal roughly $99 billion, while 1% across all employer-based defined-contribution plans would produce about $138 billion.
Long-term performance data adds context. Bitcoin delivered a cumulative return of roughly 20,050% from 2016 to 2025, compared with the S&P 500 total return of approximately 300%. Bitcoin won seven of ten calendar years against the S&P 500 over that period, but its annualized volatility was approximately 42% in 2025, about 2.6 times the S&P 500's long-term average of roughly 16%. Spot Bitcoin ETFs held just over 1.2 million BTC as of mid-July 2026, representing about 5.77% of total supply, with combined assets around $117.5 billion.
The bull case depends on converting access into allocation. CBO projects a $1.9 trillion federal deficit in fiscal 2026, with debt held by the public rising from 101% of GDP in 2026 to 120% by 2036. Asset managers use that backdrop when presenting Bitcoin as an alternative monetary asset. However, the bear case develops if access widens but allocations stall due to volatility, client preferences, or portfolio mandates. Bitcoin trades near $63,527, yet Grayscale expects ownership to keep broadening as deficits persist, blockchain finance reaches institutions, and younger investors gain financial assets.
