Bitaxe Supra 401 — Rentabilidade Mineração
Visão geral
The Bitaxe Supra 401 is part of an open-source single-chip Bitcoin miner family released February 2024, built around a Bitmain BM1368 ASIC recovered from S21 hashboards — 0.7 TH/s at 21.4 J/TH on 15 W. Bitaxe is licensed under CERN-OHL-S-2.0 with full schematics, BOM, and firmware published on GitHub (skot/bitaxe, 1.3k+ stars). The project's purpose is not to rival industrial ASICs on profitability — it is a participation device: solo lottery mining via public-pool.io or solo.ckpool.org, hands-on learning of the Bitcoin protocol stack, and a tangible counterweight to mining centralization. Within the Bitaxe lineup the Supra sits between the entry-level Ultra (0.4 TH/s) and the current flagship Gamma 601 (1.2 TH/s, 12.5 J/TH). Typical buyers: home solo miners chasing the lottery upside, hackerspaces, and sovereign-individual enthusiasts.

Impacto do halving 2028
The April 2028 halving cuts the block subsidy from 3.125 to 1.5625 BTC. For pool mining via the Supra 401 (public-pool.io style), daily revenue mechanically halves: ~$0 today, ~$0 post-halving. For solo lottery mining (CKpool solo), the lottery odds themselves don't change — they are hashrate-relative — but the prize halves: 1.5625 BTC + transaction fees per block instead of 3.125 BTC + fees. At plausible BTC prices in the 2028 window ($80–120k), a single Supra 401 block hit still pays in the $125–190k range. The Bitaxe's broader role — learning, sovereignty, network decentralization — is unaffected by the halving; the device runs the same way pre and post.

Perguntas frequentes
What can I expect when running a Bitaxe Supra 401?▾
Three layers. (1) Pool mining via a service like public-pool.io: ~$0/day in payouts at the current hashprice — symbolic revenue. (2) Solo lottery mining via solo.ckpool.org: no daily payout, but a long-tail probability of finding a full block (3.125 BTC + fees today, ~$300k+ at current BTC price). (3) Non-financial value: hands-on learning of the Bitcoin protocol stack, hardware tinkering, direct participation in network decentralization. Most owners run a Bitaxe for layers 2 and 3, treating layer 1 revenue as background noise.
What does it cost to run a Bitaxe Supra 401?▾
Hardware: ~$200 retail, $100–150 second-hand or DIY. Electricity: 15 W × 24h × 365 days = 131 kWh/year. At $0.10/kWh that is $13/year, at $0.20/kWh (premium retail) $26/year. Network: Wi-Fi or Ethernet, no extra hardware needed. Cooling: a small heatsink and fan are part of most Supra builds — no separate infrastructure. Total year-1 cost lands around $150–230, comparable to a video game console accessory or a mid-range DIY electronics kit. Pool revenue offsets a portion of the electricity bill at retail rates; below $0.05/kWh you reach electricity break-even.
What are the real solo lottery odds with a Bitaxe Supra 401?▾
Solo mining is a Poisson lottery: your chance of finding a block is your hashrate ÷ network hashrate, multiplied by 144 blocks/day. With the Supra 401 at 0.7 TH/s against ~600 EH/s, that is ~0.0000168% per day, or ~0.006% per year (1 in ~16,300). The mean time to a hit is ~16,300 years — that's the average, not a deadline; the Poisson tail leaves a real (long-tail) chance any given month. Solo block hits with low-hashrate gear get reported on solo.ckpool.org and public-pool.io block feeds — they happen, they're just rare. As a yearly lottery-ticket equivalent, the odds beat a single Powerball draw (1 in 292 million).
How do I set up solo mining with a Bitaxe Supra 401?▾
Flash AxeOS firmware (skot/esp-miner on GitHub) — most retail Bitaxes ship pre-flashed. Connect the Supra via Wi-Fi or Ethernet through the AxeOS web setup screen. Configure your pool: for true solo lottery use stratum+tcp://solo.ckpool.org:3333 (full block reward goes to you if your hashrate finds the block), or stratum+tcp://public-pool.io:21496 for low-fee solo-style pooled rewards. The username is your BTC address — that's where any reward lands. Save and the Supra starts hashing within seconds. The AxeOS dashboard shows live hashrate, accepted shares, current network target, and chip temperature.
Bitaxe Supra 401 vs Bitaxe Gamma 601 — which one to pick?▾
The Gamma 601 is the newer flagship: 1.2 TH/s at 12.5 J/TH (15 W) using the BM1370 chip from S21 Pro hashboards. Same power draw as the Supra, ~70% more hashrate, ~40% better efficiency — strictly superior for both pool mining and solo lottery odds. For a fresh build today, the Gamma 601 is the obvious pick. The Supra 401 retains value in two cases: a sharp secondary-market discount, or a personal/educational preference for the BM1368 chip generation. Both share the same firmware (esp-miner) and the same CERN-OHL-S-2.0 license.
