Is Crypto Mining Still Profitable in 2025? A Realistic Breakdown by GPU, ASIC, and Electricity Cost?
Short answer: Yes — but only for efficient ASICs at low electricity prices. GPUs are mostly not broadly profitable in 2025 unless you have very cheap (or free) power or you’re targeting a lucky small coin. Below is a realistic, evidence-backed breakdown and quick math you can reuse. Why profitability changed (quick context) Bitcoin’s block reward halved in 2024 to 3.125 BTC per block — that permanently reduced miner revenue per unit of hashpower. At the same time network hashrate and difficulty are at record highs in 2025, so any single miner’s share of rewards is smaller. Example: network hash ~ ~946–980 EH/s and difficulty at ATH levels in Aug 2025. How to think about profitability (formula) Daily BTC (or coin) revenue ≈ (your_hash / network_hash) × blocks_per_day × reward_per_block × coin_price. Daily profit = daily revenue − (power_kW × 24 × $/kWh) − pool/hosting fees − other OPEX. Example 1 — Modern ASIC (Bitmain Antminer S19 XP) Inputs & ...
