When Fidelity Crypto Industry and Digital Payments ETF (NYSEARCA:FDIG) peaked at $58 in late November 2025, crypto bulls were riding high. The fund has declined substantially since then, now trading around $42.
The selloff wasn’t unique to FDIG. Bitcoin dropped 15% from its November peak of $107,482 to around $91,000 today. FDIG tracked Bitcoin’s decline almost perfectly, suggesting the fund provides diversified exposure to the crypto ecosystem without managing digital wallets.
Why Bitcoin Mining Profitability Matters More Than Bitcoin’s Price
FDIG allocates roughly 31% to Bitcoin mining companies including Applied Digital, Iren, Cipher Mining, and Marathon Digital. These are operational businesses with electricity costs, equipment depreciation, and profit margins that fluctuate based on mining difficulty and hashrate.
Bitcoin mining difficulty hit all-time highs in late 2025, climbing to over 148 trillion. When difficulty rises, miners need more computational power to earn the same Bitcoin rewards, squeezing profitability. Hashprice, the revenue miners earn per unit of computing power, fell roughly 30% throughout 2025. This explains why mining stocks underperformed Bitcoin and why FDIG’s heavy miner allocation has been a drag.
The macro factor to watch in 2026 is whether Bitcoin’s price can climb faster than mining difficulty increases. If Bitcoin rallies to the $120,000 to $150,000 range that several analysts forecast, miner profitability improves dramatically even with elevated difficulty. Quarterly earnings reports from FDIG’s top mining holdings show whether hashrate expansion translates to revenue growth. When miners add capacity but revenues stagnate, that signals profitability challenges.
The Hidden Bitcoin Exposure Inside FDIG
FDIG’s largest holding represents 34% of the portfolio. Based on the fund’s structure and Fidelity’s product lineup, this is almost certainly the Fidelity Wise Origin Bitcoin Fund (NYSEARCA:FBTC | FBTC Price Prediction), Fidelity’s spot Bitcoin ETF that launched in January 2024. That means FDIG gives you roughly one-third direct Bitcoin exposure and two-thirds exposure to crypto infrastructure stocks.
This changes the risk profile. Direct Bitcoin exposure through FBTC charges just 0.25% annually, while FDIG’s 0.39% expense ratio covers both the Bitcoin position and active management of the equity sleeve. The fund’s 79% portfolio turnover suggests active rebalancing among crypto stocks, which can add value during volatile periods.
Fidelity’s monthly fact sheets and holdings files show FDIG’s actual composition. If the Bitcoin allocation drops below 30%, the fund becomes more of a pure crypto stock play, amplifying both upside and downside relative to Bitcoin’s price moves.
BITQ Takes Different Approach to Crypto Exposure
The Bitwise Crypto Industry Innovators ETF (NYSEARCA:BITQ) gained 13% over the past year while FDIG declined 15%, a 28 percentage point performance gap. BITQ spreads exposure more evenly across crypto exchanges, payment processors, and blockchain infrastructure companies, with less concentration in the mining sector. Unlike FDIG, BITQ doesn’t offer direct Bitcoin exposure.
The Bottom Line
Bitcoin mining profitability metrics like hashprice and difficulty adjustments indicate whether FDIG’s miner holdings will recover. Fidelity’s documents show the fund’s actual Bitcoin allocation at the current $42 per share price.
