Post-halving Bitcoin: where small miners actually went
Three years after the April 2024 halving cut block subsidies to 3.125 BTC, Bitcoin mining has consolidated into a utilities business: publicly listed operators, hosting contracts, and a global hashrate measured in hundreds of exahashes per second. Difficulty keeps ratcheting upward between halvings, and the miners still profitable at scale are the ones with cheap power — hydro, flare gas, stranded energy.
What changed for the small miner
A home ASIC pointing at BTC competes with all of that. At ~700 EH/s network-wide, a 100 TH/s farm is a rounding error; a 1 TH/s Bitaxe is a rounding error of a rounding error. Pooled BTC mining pays home devices in cents per month. Nothing about that is a secret — and it's exactly why small SHA-256 hardware migrated during 2025–2026 toward community forks of Bitcoin: same algorithm, same miner firmware, but a network of a few TH/s instead of a few hundred EH/s.
The fork ecosystem matured
The interesting 2026 development is that several SHA-256 chains crossed from 'experiment' to 'functioning ecosystem': multiple independent pools, working explorers, at least one liquid venue, and — in the case of Bitcoin Purity (BTC1) — a stated governance narrative that attracts real community hashing. None of them challenge Bitcoin's market cap; all of them offer something BTC structurally cannot: a network where one home ASIC is a visible share of consensus.
Practical takeaways
- Efficiency still matters, less critically. On small chains, variance dominates efficiency: your share of network hashrate matters more than 5 J/TH vs 15 J/TH.
- Electricity is the floor. At 15–25 W, a Bitaxe is roundoff money anywhere; at 3000 W, chain-choice math changes completely.
- Check pools, not promises. Multiple independent pools finding blocks (like on the fork checklist) is the health signal that matters.
The 2026 compromise is clear: industrial miners mine Bitcoin, home miners mine Bitcoin's ecosystem. The hardware is identical — only the target chain differs.
FAQ
- Is Bitcoin mining still profitable for individuals in 2026?
- At industrial scale with cheap power, yes. For home miners against hundreds of exahashes, BTC payouts are symbolic — which is why home SHA-256 hardware moved to community fork chains where a small rig is a meaningful share of the network.
- When is the next Bitcoin halving?
- Around April–May 2028, at block 1,314,000 — subsidies drop from 3.125 to 1.5625 BTC. Difficulty between halvings keeps rising, so per-hash margins shrink continuously, not just at halvings.
