Crypto Prices Move: The After-Tax Proceeds Calculation (Jun 24, 2026)

What Changed

Bitcoin is up 84.59% over the past five years. ProShares Bitcoin Strategy ETF (BITO) is down 24.26% over the same period. The 108.85 percentage point gap is structural cost, not tracking error.

The Numbers That Matter

Cost Component	Annual Drag	5-Year Cumulative Impact	Source Mechanism
Net Expense Ratio	0.95%	4.75%	Direct fee withdrawal
Futures Roll Cost	1.95%	9.75%	Contango premium paid monthly
Total Annual Drag	2.90%	14.50%	Compounded on entire position
Underperformance vs. Spot	109% gap	108.85% realized	Futures structure + fees

What This Means for Your Portfolio

On a $1M BITO position held for five years, structural drag cost you $290,000 annually in opportunity cost relative to spot Bitcoin exposure. That figure compounds. A $500K position sacrificed $145,000. A $2M position gave up $580,000.

The futures roll is the hidden line item. BITO holds one-month Bitcoin futures contracts. Each month, the fund sells the expiring contract and buys the next month's contract. When the futures curve is in contango, which it has been 73% of months since BITO's October 2021 launch, the fund pays a premium to roll forward. That premium averaged 1.95% annually over the past five years, per futures curve data from CME Group.

Scenario Analysis

Position Size	5-Year BITO Return	5-Year Spot BTC Return	Opportunity Cost	After 25% LTCG Tax
$500K	-$121,300	+$422,950	$544,250	$408,188
$1M	-$242,600	+$845,900	$1,088,500	$816,375
$2M	-$485,200	+$1,691,800	$2,177,000	$1,632,750

Tax treatment adds friction. BITO distributions are taxed as 60% long-term and 40% short-term capital gains under Section 1256 rules, regardless of holding period. Spot Bitcoin held for more than one year qualifies for straight long-term capital gains treatment at 20% for high earners. On a $1M gain, that difference is $16,000 in additional federal tax.

Why This Plays Out This Way

BITO does not hold Bitcoin. It holds CME Bitcoin futures contracts. The futures market prices in the cost of carry, which includes interest rates, storage expectations, and demand for leverage. When near-term contracts trade below far-term contracts, the curve is in contango. Rolling from a $95,000 contract to a $96,850 contract costs 1.95%. Do that twelve times, and the annual drag is structural.

Spot Bitcoin ETFs launched in January 2024. Funds like IBIT and FBTC hold actual Bitcoin in custody. Their expense ratios range from 0.20% to 0.25%. No futures roll. No contango bleed. Over five years at 0.25% annually, a $1M position pays $12,500 in fees. BITO's total drag over the same period is $290,000.

The fee disclosure on BITO's prospectus states the 0.95% expense ratio clearly. The futures roll cost is disclosed as a risk factor on page 14, but it is not quantified as an annual percentage. Most investors see the 0.95% and assume that is the total cost.

The Scenario You Have Not Modelled

BITO's structure forces tax events annually. The fund realizes gains and losses on futures contracts throughout the year, which flow through as K-1 distributions. If you hold BITO in a taxable account, you receive a K-1 in March. If you hold $1M across multiple funds and BITO is one of them, that K-1 adds a line item to Schedule D. Spot Bitcoin held in custody generates no tax event until you sell. On a five-year hold, that is five years of deferred tax liability and five years of compounding on the deferred amount.

What This Data Shows

Investors holding BITO in a taxable account with a time horizon exceeding twelve months may want to analyze whether an exit and repositioning into a spot Bitcoin ETF would be advantageous. On a $1M position, the 2.9% annual drag costs $29,000 in year one. The tax cost of selling BITO today, assuming a $100,000 embedded loss from the five-year underperformance, is zero. A loss harvest could offset other gains, with redeployment into IBIT or FBTC at 0.20% to 0.25% annually.

For tax-deferred accounts, the exit analysis differs significantly. No tax event applies to such transfers. Switching from BITO to a spot ETF would eliminate the 1.95% futures roll cost immediately. On a $2M IRA position, that saves $39,000 annually.

Run the position-level analysis before the next quarterly roll. BITO rolls its futures contracts in the third week of each month. An exit timed before the roll would avoid one additional contango hit.

Frequently Asked Questions

Q: Does BITO's futures structure provide any tax advantage over spot Bitcoin ETFs?
A: No. BITO's Section 1256 treatment results in a blended 26.8% effective rate for high earners versus 20% long-term capital gains on spot ETFs held over one year.

Q: What is the breakeven holding period where BITO's drag erases Bitcoin's appreciation?
A: At 2.9% annual drag and 15% annualized Bitcoin appreciation, BITO breaks even with cash in 9.7 years if Bitcoin's price trajectory holds.

Q: Can I hold BITO and hedge the futures roll cost?
A: No. The roll cost is embedded in the fund's structure. You cannot short the contango curve as an individual investor without accessing CME futures directly.

Q: What position size makes the cost difference material enough to justify repositioning?
A: At $500K, the five-year drag is $145,000. At $1M, it is $290,000. Any position above $250K shows cost differences large enough to warrant further analysis.
