Two Currencies, One Operation

Bitcoin miners earn BTC, while electricity, hosting, repairs, and other operating expenses are typically priced in fiat currency. Tracking both helps miners answer two different questions: how much BTC did the operation earn, and how does the fiat value of those earnings compare with its costs?

Neither view is sufficient on its own. BTC earnings can fall while their fiat value rises, and higher BTC earnings do not necessarily mean higher profit if costs also increase. Miners who need to pay bills must also track actual cash receipts and payments: the reference-price value of unsold BTC is not cash in the bank.

Bitcoin Mining Earnings Are Denominated in BTC

The Bitcoin block reward consists of the block subsidy and transaction fees. The subsidy is currently 3.125 BTC per block, following the April 2024 halving. Transaction fees are a separate, variable component, not part of the fixed subsidy. Bitcoin.org

In pool mining, miners submit shares that meet a target set by the pool. This target is generally higher—and therefore easier to satisfy—than the Bitcoin network target. Most shares do not qualify as blocks. Occasionally, a miner finds a share that also meets the network target, allowing the pool to submit the corresponding block to the network. The pool allocates earnings according to its payment method. Bitcoin Developer Guide

BTC credited by the pool measures mining earnings, not the amount of computational work directly. Hashrate and difficulty-weighted accepted shares help assess contributed work; raw share counts are not comparable when share difficulty differs. BTC withdrawals are a separate record because they can include earnings credited in earlier periods.

BTC Value, Mining Profit, and Cash Flow Are Different

For a simple internal comparison, miners can calculate:

Reference-price value of BTC earnings = BTC credited × BTC price in the chosen fiat currency

The price convention should be stated and applied consistently. For example, a miner could value each day's credited BTC at that day's average BTC/USD price and add those daily values for a monthly comparison. A period-end price instead shows what the period's earnings would be worth at that point in time.

This valuation is not automatically accounting revenue, profit, or cash proceeds:

• Accounting revenue follows the applicable recognition and measurement policy. Mining revenue may be recognized before BTC is sold.
• Profit depends on the revenue or valuation basis used and the costs included.
• Cash flow tracks actual receipts and payments. Selling BTC generates fiat proceeds; holding it does not by itself generate cash to pay an electricity bill.

MARA's financial reporting, for example, describes recognizing noncash mining consideration when the relevant performance obligation is satisfied, rather than waiting for a BTC sale. That illustrates why reported mining revenue and sale proceeds are different concepts. MARA 2025 Form 10-K

Define Which Mining Costs You Are Comparing

Electricity is a major recurring mining expense, but it is not the whole cost of an operation. Hosting, maintenance, repairs, labor, and other operating expenses may also apply. If a hosting charge already includes electricity, do not add the same power cost again.

The cost boundary should match the question. A comparison against electricity alone shows whether the valued earnings exceed that electricity cost. It does not establish overall profitability. A broader profit analysis may include equipment depreciation and financing interest, while a cash-flow review tracks equipment purchases and debt-principal repayments as cash outflows. These should not all be combined as if they were the same type of expense.

Similarly, if BTC credited is already net of pool fees, do not deduct those fees a second time.

Pool Rules Affect the Amount and Timing of Earnings

ViaBTC's PPS+ method uses PPS for the block subsidy component and PPLNS for the transaction-fee component. Its published fees are 4% and 2%, respectively. Under standalone PPLNS, both components use PPLNS with a published 2% fee. ViaBTC Help Center

Timing also differs: ViaBTC documents hourly payouts for the PPS component, while PPLNS calculations use the miner's hashrate share over the last five difficulty rounds when a found block reaches six confirmations. These are ViaBTC-specific rules, not universal pool conventions. ViaBTC Help Center

For a review of credited earnings, use the BTC actually credited during the selected period. A mining calculator provides an estimate, and actual results can differ as difficulty, transaction fees, and pool luck affect the relevant reward components. Settlement timing can also shift credits between reporting periods, so a short-term change in credited BTC does not necessarily indicate a change in hardware performance. ViaBTC Help Center

Compare Earnings and Costs Over the Same Period

Use a consistent reporting window for BTC credits, price conversion, and allocated operating costs. ViaBTC's Profit Detail statistics use UTC+8. If a utility bill covers a different period, allocate the relevant cost to the earnings window and label any estimates. Simply noting a mismatch does not make the figures comparable. ViaBTC Help Center

Keep power and energy units separate. Power draw is measured in kilowatts (kW); electricity consumption over time is measured in kilowatt-hours (kWh). For a constant load:

Energy consumed (kWh) = Power (kW) × Operating time (hours)

Actual metered consumption is preferable when available, especially if equipment does not run continuously at the same power level.

An Illustrative Daily Comparison

Suppose a miner receives 0.00010000 BTC, net of pool fees, for one day. Using a hypothetical reference price of $80,000 per BTC:

The $3.68 difference excludes other costs and is not total mining profit. If the BTC remains unsold, the $8.00 is a reference valuation, not a cash receipt. If sold, actual proceeds depend on the execution price and any selling fees.

Why BTC Production and Fiat Revenue Can Move Apart

MARA's 2025 filing provides a real-world example. Excluding production attributable to its ADGM equity-method investee, the reported figures imply 8,619 BTC in 2025, down from 9,048 BTC in 2024. These comparable figures are calculated by subtracting ADGM's contribution from the filing's production totals. Bitcoin mining revenue nevertheless increased from $599.436 million to $872.401 million, primarily because a higher average price of BTC mined more than offset lower production. MARA 2025 Form 10-K

The example shows why fiat revenue alone can conceal lower BTC production. It does not establish a corresponding increase in cash receipts or profit.

Using Both Views Together

Track BTC credited to understand earnings, and compare its consistently calculated fiat value with clearly defined costs for the same period. Keep withdrawals and BTC sale proceeds separate so transfers, earnings, and cash receipts are not confused.

When something changes unexpectedly, use operational data to investigate. Hashrate, uptime, and rejected-share data can help explain an earnings change alongside difficulty, reward conditions, and pool settlement rules. Pool-estimated hashrate and local ASIC hashrate provide different views and should not be treated as interchangeable.

Do not subtract rejected or stale shares again as a separate financial cost when starting from actual credited earnings; any resulting reduction in rewards is already reflected in that earnings figure. Use those share statistics to diagnose problems instead.

FAQ

Does a higher BTC price mean I earn more BTC from mining?

No. A higher market price alone increases the fiat value of a given amount of BTC; it does not increase BTC output. Mining earnings depend on contributed work, network difficulty, the subsidy, transaction fees, and the pool's payment rules.

Should I use BTC credited or BTC withdrawn for a period's earnings comparison?

Use BTC credited for a comparison of credited mining earnings. Withdrawals can include earlier earnings and reflect transfer timing. If you are assessing cash available for fiat bills, track actual BTC sale proceeds and cash payments separately.

Is fiat value minus electricity cost my mining profit?

It is only a comparison against electricity cost. Other expenses may still need to be included, and the fiat value of unsold BTC is not realized sale proceeds. State both the valuation basis and the costs covered.
