How much of what holding the coin gave did a holder of the fund keep?
A percentile among the 24 spot crypto ETPs with a full year. It is a position in a set, not a rating, and neither end of it is a recommendation. All crypto ETFs ranked by it · How it is computed
The same coin, two trusts
BTC and OBTC hold the same asset. Both are 1933 Act trusts holding Bitcoin through a custodian, so neither has a portfolio to compare: the whole of each fund is one line. Over the days each has traded, BTC finished 0.47 of a percentage point ahead of Bitcoin and OBTC 8.6% ahead once both returns are compounded, but the two are not stated in the same unit, so neither figure is set against the other here. That gap is the fee, the custody, the creation and redemption friction and the market’s pricing of the shares, compounded into one figure. OBTC has 1,265 more days of record than BTC, and a longer record is a longer window over which a cost can show itself.

BTC in plain words
BTC holds Bitcoin through a custodian and trades on an exchange, so a holder gets the coin’s return inside a brokerage account rather than a wallet. Over the year to Sep 11, 2026, Bitcoin moved −33.2% and BTC returned −32.7%. That leaves it 0.47 of a percentage point ahead. That difference is the fee, the custody cost, the friction of creating and redeeming shares in blocks, and whatever the market paid for the shares rather than for the coin, all of it together. It is the only figure on this page the sponsor does not publish itself. BTC charges 0.15% a year and still finished 0.5% ahead of Bitcoin, which a fee cannot do on its own. On a chain with nothing to stake, a fund cannot earn its way past the asset it holds: what moved is what the market paid for the shares. A spot trust is not a registered investment company. It files a 10-K rather than an N-PORT, and its holding is one line: the Bitcoin it custodies.
OBTC in plain words
OBTC holds Bitcoin through a custodian and trades on an exchange, so a holder gets the coin’s return inside a brokerage account rather than a wallet. Over the year to Sep 11, 2026, Bitcoin moved −33.2% and OBTC returned −27.4%. That leaves it 8.6% ahead once both returns are compounded. Over a window this long the two returns cannot simply be subtracted. Doing it would read +5.7 pts, which is arithmetically correct and describes nothing a holder can act on: what the figure above states is the gap between the two growth factors, so a fund that kept 109% of what holding the coin gave says exactly that. OBTC charges 0.49% a year and still finished 8.6% ahead of Bitcoin, which a fee cannot do on its own.
