Since the SEC approved spot Bitcoin ETFs in January 2024, investors have had more than a dozen exchange-traded funds giving direct exposure to the price of Bitcoin without custodying the asset. The inevitable question is: which is the best? The honest answer is that it depends on your profile, because they all do essentially the same thing. This comparison ranks the main ones by the criteria that truly differentiate them.
What makes a Bitcoin ETF "better"
Start with the most important point: all spot ETFs track the same asset, the price of Bitcoin, with the same backing (physical BTC in custody). None "yields more" than another by magic. So the real differentiators are four: the annual fee (TER), which erodes your return each year; the size and liquidity (AUM and volume), which determine bid-ask spreads and ease of entry and exit; the issuer, for reputation and solvency; and the custodian, which holds the Bitcoin backing the fund. What should NOT weigh is "past performance," because they all follow the same BTC curve.
The big ones by size and liquidity
IBIT, BlackRock's iShares Bitcoin Trust, is the dominant spot ETF by far: the largest by assets and the most liquid, which translates into tighter spreads and better execution, especially on large orders. Its TER is 0.25%. For many institutional investors, IBIT's liquidity matters more than a couple of basis points of fee.
FBTC, Fidelity's Wise Origin, is the second major reference, also with a 0.25% TER and with the particularity that Fidelity custodies the Bitcoin internally (Fidelity Digital Assets) rather than delegating to Coinbase like most.
The cheapest by fee
If your priority is minimising long-term cost, the TER ranking is clear: MSBT from Morgan Stanley is the cheapest (0.14%), followed by EZBC from Franklin Templeton (0.19%), and BITB from Bitwise and HODL from VanEck (both 0.20%). ARKB from ARK·21Shares is at 0.21%. The IBIT, FBTC, BTCO (Invesco·Galaxy), BTCW (WisdomTree) and BRRR (CoinShares·Valkyrie) block trades at 0.25%. Note that several issuers applied temporary fee waivers at launch; check the current TER before buying, because those promotions expire.
The GBTC case: the most expensive, and why
GBTC, the Grayscale Bitcoin Trust, is the outlier. It keeps a TER of 1.5% — six times more expensive than its competitors — because it wasn't born as an ETF but converted from a pre-existing closed trust that had been accumulating Bitcoin for years. That high fee has driven continuous outflows toward cheaper alternatives, though it retains relevant AUM by inertia and the tax cost some holders would face selling and rebuying. For a new investor, GBTC is hard to justify today versus an IBIT or a BITB.

The caveat for the EU investor
Here's the fine print almost no one tells: if you invest from the EU, you cannot buy any of these ETFs. The European PRIIPs rules require a document (KID) that US ETFs don't issue. We explain it in detail, with the regulated alternatives (the European Bitcoin ETPs from iShares, 21Shares, CoinShares and others), in the guide to Bitcoin ETFs from the EU. This comparison therefore serves as a global market reference and to understand what the ETPs you can buy actually track.
Beyond the ETF: when you want more than passive exposure
A spot ETF is the cleanest form of passive exposure to the Bitcoin price, but by design it does nothing more: it doesn't amplify, generate income or pay any dividends. If you want exposure with its own appreciation engine, listed Bitcoin treasuries (like Strategy or Metaplanet) add the mNAVmNAVMultiple on Net Asset Value: how a treasury company trades relative to its BTC.View term → effect and the growth of BTC per shareBTC per ShareBitcoin per fully diluted share: the denominator of BTC Yield.View term → — you can see it in the MSTR vs IBIT comparison. And if you want income, the preferred shares of those treasuries pay a fixed dividend of 8% to 13% a year. They are different tools for different objectives.
