BITU’s 31% Plunge vs. Bitcoin’s 10% Dip: The Hidden Cost of Leveraged Crypto ETFs
The ProShares Ultra Bitcoin ETF (NYSEARCA:BITU) was designed for one thing: to deliver twice the daily return of Bitcoin, without the hassle of holding the cryptocurrency directly. Through swaps tied to the Bloomberg Bitcoin Index and a 0.98% expense ratio, the pitch is straightforward. But the reality has been anything but.
Year to date, Bitcoin is down roughly 10%. A naive 2x expectation would put BITU at a 21% loss. Instead, BITU has cratered 31%. Over the trailing twelve months, Bitcoin fell 17%, while BITU lost 53%. That gap—the so-called “decay tax”—isn’t a bug. It’s a feature of how leveraged ETFs work, and it’s costing holders far more than most realize.
The mechanism is simple but punishing. BITU resets its leverage daily. If Bitcoin drops 10% one day and rises 10% the next, it ends slightly below its starting point. BITU, however, falls 20% then rallies 20%, leaving a deeper hole. Over time, in choppy markets, that compounding effect erodes value relentlessly. Since its 2024 inception, Bitcoin has returned 37%, while BITU has lost 40%—the same asset class, leveraged, going in opposite directions over a multi-year window.
“I bought BITU thinking I was just getting a turbocharged version of Bitcoin,” said Mark Delaney, a 34-year-old retail trader from Austin, Texas. “Now I’m down 40% and Bitcoin itself is barely off its highs. It feels like a trap for anyone who doesn’t read the fine print.”
Not everyone is surprised. Dr. Elena Vasquez, a financial analyst at a New York-based wealth management firm, notes: “Leveraged ETFs are trading tools, not investments. They’re designed for daily rebalancing, and holding them through volatile periods is mathematically destructive. The decay is baked in.”
But the frustration is palpable. Jake Morrison, a crypto enthusiast and part-time options trader in Miami, didn’t hold back: “This thing is a joke. I trusted the ‘2x Bitcoin’ label and got crushed. It’s not just decay—it’s a slow bleed that most people don’t see coming until it’s too late. The ETF industry should put a warning label on these products.”
The recent rally in Bitcoin—up 16% over the past month in a relatively clean trend—shows the flip side. BITU returned 30% during that stretch, nearly matching a true 2x. Trending markets reward leverage. But the historical record is clear: Bitcoin has repeatedly suffered 50%-plus drawdowns. A straight-line 50% drop would nearly wipe out a 2x daily product. A volatile 50% decline would be even worse, as decay compounds the losses.
Financing costs add another layer. BITU’s swaps are priced off short-term funding rates. With the Fed funds rate at 3.75% and the 10-year Treasury yielding 4.40%, those costs are manageable but persistent. They accrue daily, silently dragging on returns.
For traders, the lesson is clear. BITU works as intended for a single trading day. Held longer, it’s a bet that Bitcoin will trend in one direction without major reversals. History suggests that’s a losing wager. The 36-percentage-point gap between Bitcoin’s 17% decline and BITU’s 53% loss over the past year is the price of ignoring the structure. Position size and holding period matter—and for most, the answer is shorter than they think.
