Sazmining Review
Hands-off Bitcoin mining with hardware you own, powered by 100% renewable energy across four continents.
Why We Recommend Sazmining
Sazmining stands out in the mining-as-a-service space by solving the core trust problem: you actually own your hardware. Unlike cloud mining contracts where you're essentially renting hashrate with no underlying asset, here you purchase ASIC miners at fair market cost (around $5K for a Bitmain S21) and retain full ownership with serial number tracking. Mined Bitcoin goes directly to your personal wallet weekly—no company custody, no withdrawal approval process, just "wild sats" flowing to your cold storage. The non-custodial payout model eliminates counterparty risk that has burned so many in the mining space.
The aligned incentive structure builds additional confidence. Sazmining takes a revenue share (15-20% depending on location) only from what you actually mine, plus a transparent monthly service fee covering electricity at fixed rates around $0.047/kWh. This means they're financially motivated to maximize your uptime and efficiency rather than just collecting fees regardless of performance. Their renewable energy commitment is genuine—hydro and solar facilities across Paraguay, Ethiopia, Norway, and the USA—backed by positive Trustpilot reviews and community feedback since their 2018 founding. Users consistently praise responsive support via chat, email, and Telegram, plus monthly town halls that maintain transparency around operations.
Best For
Sazmining is ideal for Bitcoin believers who want exposure to mining economics without becoming hardware experts or dealing with noise, heat, and electricity negotiations at home. If you're drawn to the idea of earning "virgin" Bitcoin directly from the network but don't want to manage ASICs yourself, this fills that gap perfectly. The white-glove service works even for single-rig buyers, with deployment typically completed within weeks and 24/7 monitoring via an intuitive dashboard showing hashrate, energy consumption, and earnings in real-time.
Long-term stackers thinking in 3-5 year horizons will appreciate the fixed electricity contracts that protect against price hikes and the peer-to-peer resale options when upgrading hardware. Bulk buyers ordering 20+ units get additional attention, making this suitable for those scaling up mining exposure over time. The eco-conscious angle appeals to Bitcoiners who want their stack accumulated via renewable energy rather than fossil fuels.
That said, this isn't for traders seeking quick returns or anyone expecting guaranteed profitability. Network difficulty increases mean some users report 27-month break-even periods versus initial 15-month estimates. If you'd rather just DCA on an exchange, the math often favors that approach in rising hashrate environments. But for those who philosophically prefer mining their own coins with hardware they own, Sazmining removes the operational headaches while keeping you in control of the Bitcoin.

Considerations
Only rigs purchased through Sazmining are accepted—no bringing your own hardware. Post-warranty repairs cost extra, profitability fluctuates significantly with Bitcoin price and rising network difficulty, and some users report effective BTC acquisition costs exceeding exchange prices after fees. No refunds once hardware is purchased.
