The Bitmain Antminer S9 Recycling, Resale Value, and Disposal (2026) guide provides detailed information on managing the end-of-life process for this specific mining device. Released in 2017 by Bitmain, the Antminer S9 is a SHA-256 ASIC with a weight of 4.2 kg and a hashrate of 14 TH/s, operating at an energy efficiency of 92.85 J/TH. This guide explores various options for dealing with the Bitmain Antminer S9 Recycling, Resale Value, and Disposal (2026), including resale, scrap recovery, hosting services, or controlled disposal methods.

Per Cambridge Centre for Alternative Finance research (2021, updated through 2024), the Bitcoin network generates an estimated 30.7 kt of e-waste per year from ASIC obsolescence. The Bitmain Antminer S9 contributes to this where it is scrapped rather than refurbished or hosted in a lower-cost region.

Status: End-of-life. Not profitable at any electricity rate above $0.02/kWh as of 2026. End-of-life consideration: The Bitmain Antminer S9 is past its profitable operating window in most electricity markets as of 2026. Buyers should plan for limited remaining hashrate productivity. Resale prices ($25-$80) reflect this. Scrap recovery may be the most economic path if your electricity cost exceeds $0.04/kWh.
Top brokers + secondary marketplaces
The most active 2026 venues for buying or selling used Bitmain Antminer S9 units:
| Broker | Profile |
|---|
| Compass Mining | Hosted-mining marketplace with built-in trade-in valuation. Best for buyers wanting hosting + hardware bundle. US-based. |
| Kaboomracks | Telegram-based bulk broker, primary venue for institutional ASIC trading. Best for >50-unit lots. |
| SunnySide Digital | Secondary-market reseller specialising in older + tested units. US-based, transparent inspection process. |
| NiceHash Marketplace | Peer-to-peer ASIC trading platform with built-in escrow. International audience. |
| BlockwareSolutions | US-based broker + hosting provider. Strong for first-generation buyers needing setup support. |
For unit lots above 50 ASICs, Kaboomracks typically offers the highest cash bid. For single units, NiceHash Marketplace has the best price discovery via escrowed peer-to-peer trades.
Hosting + colocation options
If you want to keep the Bitmain Antminer S9 productive but can't host at home (electricity cost, noise, heat), hosted-mining facilities accept third-party-owned ASICs and run them in industrial-grade colocation:
- Compass Mining (US, Canada, Paraguay, Iceland): per-month hosting from $0.06-$0.08/kWh total cost (electricity + colocation). 12-month commitment typical.
- GoMining (Kazakhstan, US, Russia): tokenised hosting model. Sell your ASIC's hashrate as NFT-backed tokens.
- Cathedra Bitcoin (US, Canada): full-service colocation for institutional buyers.
- Riot Platforms (Texas, US): wholesale colocation for >100-unit lots.
- CleanSpark (Georgia, US): focuses on grid-stabilising mining. Accepts third-party hardware via partnership programmes.
Typical hosting profitability: $0.06/kWh hosted = profitable above ~20 J/TH efficiency. The Bitmain Antminer S9 at 95 J/TH is below the profitable hosting threshold - sell for scrap or relocate to <$0.04/kWh markets.
Tax + customs considerations
United States: ASIC purchases for mining are classified as business equipment for tax purposes. Bonus depreciation rules (IRC §168(k)) allow 100% expense deduction in year one for units placed in service before 31 December 2026 (phasing down after). Track via IRS Form 4562.
United Kingdom: ASIC sales are subject to 20% VAT for non-business buyers. Business buyers can reclaim VAT via standard input-tax claims. Mining income classified as trading or miscellaneous income per HMRC Cryptoassets Manual (December 2024 update).
European Union: VAT varies by member state (typically 19-25%). Mining income classified per local tax authority - generally as self-employment income.
Import/export: ASIC imports from China to US trigger Section 301 tariffs (currently 25%). UK/EU imports from China subject to ~10% anti-dumping duty applied since 2024. Always factor tariff cost when comparing direct-from-manufacturer vs secondary-market pricing.
End-of-life destruction options
When secondary-market resale is not economic, two compliant destruction routes:
- Specialist e-waste recycler with RCRA certification (US) or WEEE Compliance Scheme (UK/EU). Drop-off cost typically $5-$25 per unit at industrial recyclers. See our E-Waste Fines Checker for jurisdiction-specific rules.
- Component recovery by specialist scrap dealer. Aluminium chassis ($15-$30) recovers most of the residual value. PCBs go to specialist precious-metal refiners (Umicore, Aurubis, Boliden) for gold + palladium recovery.
Never: put a mining ASIC in general waste. The lithium-coin battery in many control boards is a fire risk and the PSU contains aluminium electrolytic capacitors that count as hazardous waste in most jurisdictions.
Frequently asked questions
Is the Bitmain Antminer S9 still profitable to operate in 2026?
End-of-life. Not profitable at any electricity rate above $0.02/kWh as of 2026. Profitability is highly sensitive to electricity cost - calculate your own break-even using current Bitcoin price + network difficulty + your actual cost per kWh.
What's the warranty status?
Manufacturer warranties on Bitmain Antminer units are typically 12 months from purchase, void if hashrate is below 95% of spec or the unit was modified (immersion cooling, custom firmware). Most secondary-market units are out of warranty.
Where should I buy a used Bitmain Antminer S9?
For single units: NiceHash Marketplace or SunnySide Digital with escrow. For 10+ units: Kaboomracks or direct broker outreach via Telegram. For 50+ units with hosting bundled: Compass Mining. Always insist on a 24-hour hashrate test period before final payment.
What's the resale liquidity right now?
Bitmain Antminer S9 has limited secondary-market liquidity in 2026. Expect 3-14 days to find a buyer at current market prices via Kaboomracks or NiceHash. For a faster sale at 15-25% discount, scrap dealers in Texas, Pennsylvania, and Quebec accept ASIC lots without dispute.
Can I convert Bitmain Antminer S9 for other coins (LTC, KAS, etc.)?
No. The Bitmain Antminer S9 is a single-algorithm ASIC (SHA-256) - physically can't mine other algorithms. To switch to Litecoin or Kaspa mining you need a different ASIC (Goldshell LT7 for Scrypt, IceRiver KS5 for kHeavyHash).
