New model proves miners need Bitcoin above $74k to break even on power – but other costs push it over 6 figures

A detailed analysis using a Bitcoin Mining Cost Model, applied to Riot Platforms' operations, demonstrates that while US Bitcoin miners can cover electricity costs at current market prices, they often fall short of covering broader operating and accounting expenses. The model highlights three distinct break-even layers: electricity, operating costs, and full accounting profitability, revealing a significant gap between them even after Bitcoin's price recovery.

Three Layers of Mining Economics

The study, based on current network conditions including a difficulty of 145,042,165,424,850 and a block reward of 3.125 BTC, with Texas industrial electricity at approximately $0.0667 per kWh, calculates an electricity cost of $64,635 to mine one Bitcoin. This yields a power margin of $2,565 per BTC at a Bitcoin price of $67,200. However, when Riot's non-power operating costs of about $9,809 per BTC and depreciation of $39,687 per BTC are added, the operating margin becomes negative $7,243, and the accounting profit reaches negative $46,930.

The model defines these layers as follows:

• •
  Electricity-only break-even: $64,635 per BTC. This determines if machines are worth running in the short term.
• •
  Operating break-even: Approximately $74,444 per BTC, including non-power operating costs. This indicates if self-mining covers the rest of the business operations.
• •
  Full accounting break-even: $114,130 per BTC, incorporating depreciation. This reflects the overall reported profit.

The analysis shows that miners can achieve positive power economics while still reporting weak operating or accounting results. For instance, at a $49,000 BTC price, all margins are negative. At $67,200, only the power margin is slightly positive. Profitability across all three layers, including accounting profit, is only achieved when Bitcoin reaches approximately $126,000, resulting in an accounting profit of $11,870 per BTC.

Future Projections and Cost Sensitivity

Projecting costs until the next halving in 2028, assuming Riot's hash rate ramps to 45 EH/s, the model indicates significant cumulative losses at lower Bitcoin prices. At $49,000 BTC, the cumulative accounting profit is projected at negative $997 million. At $67,200 BTC, it remains negative at -$718.7 million, despite a positive cumulative power margin. Even at $80,000 BTC, the cumulative accounting profit is still negative at -$522.7 million.

The study also examined cost sensitivity across different ASIC models (Bitmain S21, WhatsMiner M60S, Antminer S19 Pro) and electricity prices. It found that older, less efficient ASICs like the S19 Pro become unprofitable faster as power costs rise, while newer models maintain a competitive edge. The gap between electricity break-even and full accounting break-even is approximately $49,495 per BTC, underscoring the importance of operational efficiency and Bitcoin's price for sustained profitability.

Ultimately, the case study suggests that while miners can achieve positive power margins well below six figures, reaching consistent operating and accounting profitability requires higher Bitcoin prices, potentially retesting all-time highs around $114,000 to $126,000.
