Spot Bitcoin ETFs were supposed to be the simplest way to own crypto. Funds like the iShares Bitcoin Trust (NASDAQ:IBIT) made it easy: low fees, direct spot exposure, no wallet headaches. Buyers in early 2026 wanted clean access to crypto’s upside. Instead they got a fund tracking a coin down 29.36% year to date. The Amplify Transformational Data Sharing ETF (NYSEARCA:BLOK), which owns the companies that profit from blockchain activity rather than the coin, has gone the other way.
The Case for Spot Bitcoin ETFs, and Where It Breaks
The case for a spot Bitcoin ETF is still mostly intact. The major funds track Bitcoin within a few basis points, charge between 0.20% and 1.50%, and remove the risk of self-custody. For an investor who wants Bitcoin price exposure in a brokerage account or IRA, they do that job. The problem in 2026 is that the job has been a losing one: Bitcoin is down 23.2% over the past month and 43.12% over the past year, and a spot ETF passes that through almost cent for cent. It is a single bet. It captures none of the fees exchanges earn, the subsidies miners collect, or the operating leverage of companies built on top of the asset. Those revenue streams keep earning even when the coin falls, and the stocks can re-rate on catalysts like miners’ pivot toward AI data-center hosting.
The Alternative: a Basket of Crypto-Economy Stocks
BLOK takes the other side. It holds roughly 54 positions in blockchain and crypto-related companies, about 80% in operating businesses and only a sliver in spot Bitcoin products. Recent top holdings include Hut 8, Cipher Mining, Galaxy Digital, TeraWulf, CleanSpark, Coinbase, Robinhood, and Strategy (formerly MicroStrategy). Several of those miners have moved hash-rate capacity into AI compute hosting, a non-crypto tailwind during Bitcoin’s drawdown.
BLOK is up 11.09% year to date through June 11, 2026, against Bitcoin’s 29.36% decline. It is also up 20.79% over the past year, while Bitcoin is down 43.12%. For an investor who wanted to ride the crypto cycle, owning the equity basket rather than the coin opened a roughly 40-percentage-point year-to-date gap in their favor.
The driver is a rotation in BLOK’s top holdings. ETF Database reported its NAV rose 14.49% in May, led by Cipher Mining and Hut 8 shifting capacity toward AI data centers. TeraWulf CEO Paul Prager described the move as “repositioning towards long-term contracts in AI data centers,” recurring revenue a spot Bitcoin ETF cannot offer.
The Real Tradeoffs
BLOK carries real costs. Its expense ratio is 0.70% as of March 25, 2026, several times what the largest spot Bitcoin ETFs charge. It holds about $1.26 billion in net assets, modest enough that liquidity can get choppier under stress. And while BLOK has decoupled from Bitcoin this year, its longer-term correlation to the coin stays high.
Seeking Alpha’s Michael Del Monte called BLOK a higher-volatility vehicle strongly correlated to Bitcoin, “best suited as a satellite holding with modest allocations within a broader, diversified portfolio.” When Bitcoin rallies hard, BLOK can lag a spot ETF on pure beta, because mining operators carry costs the coin does not. Taxes matter too: selling a spot Bitcoin ETF at a gain to rotate into BLOK triggers a capital gains event, which in a taxable account with embedded gains can erase much of the swap’s value. In an IRA, the rotation is mechanical.
How to Think About the Swap
The cleanest version is a partial rotation, not an all-or-nothing switch. An investor who wants pure price exposure can keep a core spot ETF and add BLOK as the equity-side sleeve. For those whose thesis was crypto adoption rather than Bitcoin’s price specifically, shifting more toward BLOK makes more sense, because its holdings monetize the ecosystem regardless of the spot price.
Keep the honest framing in view: BLOK is up 67.95% over five years, lagging Bitcoin’s 73.92%. It is a different way to express the same theme that happens to be winning in this part of the cycle, with the coin still the cleaner vehicle for pure price exposure.
What Would Change the Call
If Bitcoin reclaims its highs and resumes a vertical move, a spot ETF will likely outrun BLOK, since miners’ costs and exchange fee compression cap the equity beta. If the miner AI pivots stall, BLOK loses the tailwind behind much of 2026’s divergence. And if its fee drifts higher or it strays from the picks-and-shovels names doing the work, the case weakens. For now, the data support treating BLOK as the more productive way to own the crypto theme, with a spot Bitcoin ETF the cleaner instrument for anyone whose only question is where the coin goes next.
