Every crypto manager reports dollar returns. Almost none report the number that matters: whether the strategy grew the amount of Bitcoin an investor's capital represents. Here is why we believe the honest benchmark for a digital-asset strategy is Bitcoin itself.
Ask most digital-asset managers how they performed last year and you will hear a dollar figure. It sounds rigorous. It is also, in this asset class, the easiest possible test to pass. In a crypto bull market, nearly everything rises against the dollar. A manager who did nothing more sophisticated than stay long looks brilliant when priced in a unit that the entire sector appreciated against.
There is a harder question, and it is the one we believe every allocator should ask: measured in Bitcoin, did the portfolio grow? If a fund charges fees, takes active risk, and finishes the year controlling less BTC than the investor's capital would have bought on day one, the investor did not need the fund. They needed a wallet.
This essay lays out the case for bitcoin denominated returns: what the measurement means mechanically, why dollar figures flatter crypto managers, the discipline the Bitcoin benchmark imposes, where dollar accounting still belongs, and how allocators can put the question to any manager they evaluate.
BTC-denominated returns measure a portfolio's performance with Bitcoin, rather than the dollar, as the unit of account. The mechanics are simple: divide the portfolio's net asset value by the Bitcoin price at each measurement date. The result is the number of BTC the portfolio represents. If that number grows over time, the strategy is adding value in Bitcoin terms.
Put differently, the measurement reframes the portfolio as a stack of Bitcoin. A fund that starts the year representing 20 BTC and ends it representing 22 BTC produced a positive BTC-denominated return of 10 percent, whatever happened to the dollar figures in between. A fund that starts at 20 BTC and ends at 17.5 BTC destroyed Bitcoin-denominated value, even if its dollar NAV rose substantially along the way.
The concept of a BTC unit of account is not an affectation. Benchmarks exist to answer a specific question: what was the investor's realistic passive alternative? For an equity fund, that alternative is an index. For a digital-asset strategy built on conviction in Bitcoin and the assets around it, the realistic alternative is not Treasury bills. It is holding Bitcoin.
The dollar is a moving target in this asset class. In the strong years, Bitcoin has appreciated against the dollar by large multiples, and most liquid digital assets have moved with it. A manager measured in dollars gets credit for all of that movement, whether or not their decisions contributed anything beyond exposure.
Consider a deliberately simple, hypothetical illustration of the arithmetic. The figures below are invented for clarity; they do not represent any fund's results, including ours.
| Measure | Start of year | End of year | Change |
|---|---|---|---|
| Bitcoin price (hypothetical) | $50,000 | $80,000 | +60% |
| Portfolio value in USD | $1,000,000 | $1,400,000 | +40% |
| Portfolio value in BTC (NAV divided by BTC price) | 20.0 BTC | 17.5 BTC | -12.5% |
In dollar terms, this hypothetical manager is up 40 percent and the year-end letter writes itself. In Bitcoin terms, the investor's capital now commands 12.5 percent less BTC than it did in January. The investor paid fees and took manager risk to end up with a smaller stack than a cold-storage wallet would have delivered. The dollar lens hides this; the Bitcoin lens makes it unmissable.
This is not an argument that dollar gains are fake. It is an argument about attribution. A rising sector pays every long-biased participant in depreciating-denominator terms. The benchmark's job is to separate what the market gave from what the manager added, and against a sector that moves with Bitcoin, only a Bitcoin benchmark does that cleanly. The same logic explains why comparing fund structures on dollar returns alone misses the point; we cover the structural side in our piece on a Bitcoin ETF versus a Bitcoin fund.
If a strategy cannot grow the amount of Bitcoin an investor's capital represents, the investor could have simply held Bitcoin.
Adopting Bitcoin as the unit of account changes manager behavior, because it changes what counts as a win. Every trade must clear a specific hurdle: will this decision result in more BTC than not making it? A rotation into an altcoin is only justified if it is expected to gain against Bitcoin, not merely against the dollar. Time spent in stablecoins is not neutral; it is an active short of Bitcoin that must be earned back. Fees are paid out of the stack and must be recovered in stack.
This is a demanding standard, and that is the point. Bitcoin has been among the strongest-performing major assets of the past decade, which makes it a benchmark that punishes activity for its own sake. A manager measured against it cannot manufacture the appearance of skill by riding sector beta. The benchmark keeps the manager honest in the most literal sense: it removes the flattering denominator.
This is how we think about our own mandate at TRU Capital. The fund combines a fundamental digital-asset allocation with proprietary algorithmic trading, and the mandate is to accumulate more Bitcoin over time. We do not claim to have beaten Bitcoin, and nothing here is a performance figure. The benchmark is not a boast; it is a constraint we volunteer for, because it is the standard we would demand as allocators ourselves.
Dollar measurement still matters wherever the investor's obligations are denominated in dollars. Spending needs, liabilities, capital calls elsewhere in a portfolio, and tax bills are all settled in fiat. United States tax liability in particular is computed on dollar cost basis, so a fund can lose ground in BTC terms and still generate taxable dollar gains. Dollar reporting is therefore necessary, not optional.
The two lenses answer different questions. The dollar lens answers: what can this capital buy in the real economy today, and what does the investor owe on it? The Bitcoin lens answers: did the manager add value relative to the passive alternative? A serious digital-asset investor needs both, in the same way a global equity investor thinks in both local currency and home currency. The mistake is not using dollars; the mistake is using only dollars, and letting a rising sector grade its own exam.
Ask any manager for their net asset value divided by the Bitcoin price at each reporting date, presented as a time series alongside the dollar NAV. Every fund already has both inputs; producing the series is arithmetic, not archaeology. A manager who runs a digital-asset strategy and cannot, or will not, show it has told you something worth knowing.
In practice, three questions cover the ground. First: since inception, has the portfolio's BTC-equivalent value grown, shrunk, or tracked the market? Second: does the team evaluate its own trades against a Bitcoin hurdle, and can they describe a trade they declined because it was unlikely to beat holding? Third: how are fees presented in BTC terms? None of these require confidential data, and all of them are more revealing than another dollar chart. For the broader diligence process, from structure and custody to lockups and minimums, see our guide on how to invest in a crypto fund.
The audience for this standard is growing. Henley & Partners, in its Crypto Wealth Report, documented a sharp rise in the number of Bitcoin millionaires worldwide in 2024, and that population thinks about wealth differently: for many of them, Bitcoin is the balance sheet, and the dollar is just a translation. An investor whose net worth is already denominated in BTC has no use for a fund that grows dollars while shrinking their stack. They are the natural constituency for BTC-denominated mandates, and managers are beginning to compete for them on exactly these terms.
We think this becomes a category. As digital assets mature from a trade into an allocation, the sophistication of the questions matures with them, and "what did you return in dollars" is a first-cycle question. The second-cycle question is the one this essay has argued for: measured in the asset you exist to compound, did you compound it? Managers who welcome that question will define the category. Managers who deflect it will be defined by it.
Our answer is on the table. TRU Capital is a private fund offered under Rule 506(c) of Regulation D, open to verified accredited investors, with a $250,000 minimum, a 12-month lockup, an open-ended structure, and a 2 percent management fee with 20 percent performance participation. The mandate is to accumulate more Bitcoin over time, and the benchmark that keeps us honest is the one we have spent this essay defending.
It means converting a portfolio's value into BTC at each measurement date, typically by dividing net asset value by the Bitcoin price, and comparing those figures over time. If the portfolio represents more Bitcoin at the end of a period than at the start, it produced a positive BTC-denominated return, regardless of what the dollar figure did over the same period.
In crypto bull markets, nearly every asset in the sector rises against the dollar, so almost any long-biased portfolio shows a strong dollar return. That figure blends manager skill with market beta. Measuring against Bitcoin strips out the sector-wide move and isolates the question that matters: did the strategy add value beyond simply holding the asset?
No. Investors live in a dollar world. Spending, liabilities, and tax obligations are denominated in dollars, and taxable events in the United States are calculated on dollar cost basis. Dollar reporting remains necessary for planning and compliance. BTC-denominated measurement is a complement that evaluates manager skill, not a replacement for dollar accounting.
Ask for the fund's net asset value divided by the Bitcoin price at each reporting date, shown as a time series. Any manager can produce this from data they already report. If a manager is reluctant to present performance in BTC terms, that reluctance is itself useful information about how the strategy compares with holding Bitcoin.
It fits strategies whose thesis centers on Bitcoin or on digital assets broadly, where holding BTC is the natural passive alternative. Strategies with other objectives, such as market-neutral yield, may warrant different comparisons. The principle generalizes: the benchmark should be the passive alternative the investor would otherwise choose.
