A dollar put into a spot crypto ETF is not quite a dollar's worth of the coin. Of the 46 funds ETFIQ can measure on Oct 14, 2026, 38 closed within a point of the coin they hold, and the typical gap across all of them is 0.20%. That number bundles together the fee, the custody arrangement, the friction of creating and redeeming shares in blocks and whatever the market happened to pay for the shares rather than the coin itself on the day measured. It is the one number on this page that no sponsor publishes on its own.
Bitcoin and Ether funds track closest to the coin. Bitcoin's 13 funds show a median difference of −0.2%, with 11 of 12 measurable funds within a point, against a median coin return of −27.5% over the period measured. Ether's 11 funds show the same median difference, −0.2%, and all 11 land within a point of Ether's −40.9%. XRP's six funds also cluster tightly, a median difference of −0.3% with all six within a point, against a coin return of +19.5%. Dogecoin's three funds post a median difference of −0.2%, all three within a point, against +11.1% for the coin.
Solana is the coin where the spread across funds is widest. Eight funds hold it, the median difference is +1.2%, and only two of the eight land within a point of the coin's +35.0% move. Individual Solana funds range from BSOL at +1.9% to QSOL at +0.5%, all on the same three-month window and against the same coin return, so the spread between them is read as the cost of holding each one rather than any difference in what Solana itself did. Avalanche shows a similar pattern in miniature: three funds, a median difference of +0.8%, two of three within a point, coin return +47.6%. Litecoin, Chainlink and Polkadot each have one or two funds and sit close to their coin, at −0.6%, −0.1% and +0.2% respectively.
Two trusts, not shown ranked against the rest, are quoted too thinly to compare on equal footing: they close unchanged on more than one trading day in twenty, so their difference against the coin reflects the days somebody traded rather than what the fund did over the full period. They are published with that caveat attached rather than placed in order with the others.
A separate set of 25 fund-windows cannot state their gap by simple subtraction once either return has compounded far enough. ETHE since January 2020 is the example on this page: it returned +627.8% against Ether's +1,854.4%, a subtraction of −1,227 points that means nothing once compounding has run that long. For those windows the site instead prints the gap between the two growth factors, which for ETHE's full record is −62.8%.
Readers can look up any ticker on ETFIQ's fund pages to see its own window, its own difference against the coin it holds, and whether that number is a simple subtraction or a compounded gap.
