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 0.09 of a percentage point behind Bitcoin and OBTC 5.0% ahead once both returns are compounded, but the two are not stated in the same unit, so neither number 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 number. 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
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 Oct 28, 2026, Bitcoin moved −28.3% and BTC returned −28.4%. That leaves it 0.09 of a percentage point behind. 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 number on this page the sponsor does not publish itself. BTC charges 0.15% a year and finished 0.1% behind Bitcoin, so the fee is almost the whole of the difference. 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.
Doing it would read +3.6 pts, which is correct and describes nothing a holder can act on: what the number above states is the gap between the two growth factors, so a fund that kept 105% of what holding the coin gave says exactly that.
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 Oct 28, 2026, Bitcoin moved −28.3% and OBTC returned −24.7%. That leaves it 5.0% ahead once both returns are compounded. Over a window this long the two returns cannot simply be subtracted. OBTC charges 0.49% a year and finished 5.0% 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.
