ProShares Ultra Bitcoin ETF (NYSEARCA:BITU) promises double the daily move of Bitcoin, and right now that means double the chaos. The fund collapsed through January and early February, with 44% losses over the past month as Bitcoin's selloff accelerated. This decline was roughly twice the magnitude of the underlying Grayscale Bitcoin Mini Trust ETF (NYSEARCA:GBTC), which fell 23% in the same period, illustrating the core risk: BITU magnifies both gains and losses through its 2x leverage structure.

The fund launched April 1, 2024 and holds $538 million in assets. It achieves 2x exposure through regulated Bitcoin futures contracts, not direct coin ownership. That structure matters because futures carry roll costs and tracking error during extreme volatility.

Bitcoin's recent crash from its late January peak created a cascading effect for leveraged holders. The magnitude of this decline translated to catastrophic losses for BITU holders who experienced the move at double intensity. This reveals why the futures-based structure amplifies risk during liquidation cascades, as each percentage point of Bitcoin's decline hits twice as hard.

The Macro Factor: Leveraged Liquidations and Fear Cycles

Bitcoin volatility is being driven by forced selling from overleveraged positions. Hong Kong hedge funds with leveraged Bitcoin bets triggered the sharp month-long selloff, according to market analysis from traditional financial news sources. When prices fall, margin calls force liquidations, pushing prices lower and triggering more margin calls. Roughly $2 billion in leveraged positions were liquidated in a single day.

This matters for BITU because the fund itself is leveraged. When the underlying asset experiences liquidation cascades, 2x exposure means getting hit twice as hard. The key macro signal to watch is Bitcoin futures open interest and funding rates, published daily by exchanges like CME and major crypto platforms. Rising open interest with negative funding rates suggests new short positions building, which can reverse violently. Sustained positive funding with high open interest indicates overcrowded longs vulnerable to washouts.

The Micro Factor: Daily Reset Risk and Volatility Decay

BITU resets its 2x leverage daily, creating path dependency. This means the fund's performance compounds in ways that diverge from simply doubling Bitcoin's move over multi-day periods. If Bitcoin falls 10% one day then rises 10% the next, you don't break even. You lose money due to the mathematical effect of percentage changes on different base values.

During February 5-6, Bitcoin dropped 14% then rallied 12%, resulting in an 8.5% cumulative loss for BITU holders even though Bitcoin only fell slightly net. This example demonstrates why volatile, choppy markets destroy value in daily-reset leveraged products regardless of the eventual direction.

Check the fund's daily NAV versus Bitcoin's performance in ProShares' fact sheets. Extended periods of high volatility without a clear trend destroy value in leveraged ETFs through this compounding effect. BITU works for short-term directional bets when you have conviction on Bitcoin's next move, but holding through violent swings like we've seen recently is a losing proposition regardless of where Bitcoin eventually settles.

The most important factor for the next 12 months is whether Bitcoin volatility subsides or remains elevated, and the most critical micro signal is monitoring daily NAV decay during choppy, trendless periods.

It’s Time To Rethink Passive Investing
