BITO Expense Ratio and Roll Cost: What You Actually Pay

BITO, the ProShares Bitcoin Strategy ETF, charges an expense ratio of 0.95% a year. That is the published figure, and it is only part of what the fund costs you. Because BITO holds expiring futures contracts rather than bitcoin, it also pays a roll cost every month - a charge that appears on no fact sheet and is usually larger than the fee itself.

What the 0.95% covers

The expense ratio is the management fee, taken out of the fund's assets a little each day. You never see a bill; the share price is simply slightly lower than it would otherwise be. For comparison, the big spot bitcoin ETFs - the ones that buy coins and store them, like BlackRock's IBIT and Fidelity's FBTC - charge somewhere around 0.20% to 0.25%. On a $10,000 holding, that difference alone is roughly $70 a year.

The roll cost, which is bigger

Each month BITO sells the futures contract about to expire and buys the next one. Later contracts usually cost a little more, so the fund habitually sells cheap and buys dear. Estimates of what that costs bitcoin futures funds annually have commonly landed in the low single digits of percent, and higher when the futures curve steepens. Add it to the fee and the all-in drag can be several times the headline 0.95%. It is the difference between buying a flat and renewing a one-month lease at whatever next month's rent turns out to be.

Why the share price makes it look worse

BITO pays out much of what it earns as monthly distributions, and every distribution comes straight off the share price. So a chart of BITO against bitcoin exaggerates the shortfall, because some of that drop is cash that already reached holders. Total return - which adds distributions back in - is the honest comparison. The gap is real. It is just smaller than the price line suggests.

If you hold BITO, look up its total return over one and three years rather than its share price, and set that beside bitcoin's own move over the same window. That one check tells you more than any fee table. Where the roll cost comes from is explained in contango and decay, and the fund's wider trade-offs in why BITO underperforms bitcoin.
