Sazmining
You buy a serial-numbered BTC miner outright; Sazmining hosts it, bills power at cost and takes 15% only on Bitcoin actually mined.
A large hosted-mining platform with real contracts and a named entity, but a 2022 counterparty crisis, unaudited capacity claims, a security interest over your hardware and a rigid 3-year default term make it a watch, not a recommendation.

Compass Mining is the largest ASIC-hosting marketplace, run by Compass Mining Inc. of Wilmington, Delaware [1]. Its product stack survives: hosted mining, a miner marketplace, and a genuinely new month-to-month "Easy Exit" line [1]. We keep it on watch because the 2022 deposit-loss history is still unacknowledged, rates and commissions are unpublished, and a flagship Iowa site is now in a zoning fight [8].
Hosted miner space across self-reported facilities (5.9 EH/s under management, 160 MW - marketing numbers unchanged since August 2025) [1], plus hardware via the marketplace, where listed miners are hashed within plus or minus 5% and ownership transfers over seven days [1]. The Easy Exit line answers the old long-term-commitment problem: month-to-month hosting, "No Deposits. No Cancellation Fees. No Long Term Commitments" [1]. The old Rackfull product is gone (404, zero archives) [1]. You own the machine; Compass handles the facility - and keeps a security interest in it.
The standard hosting agreement is where Compass earns its watch status: a 3-year initial term with 60-day non-renewal notice [4], an early-termination fee equal to remaining fees [4], a $50 de-rack fee, and $50 per unit per month storage that ends in hardware forfeiture if unpaid for ten business days [5]. The 95% "uptime guarantee" is a service-credit scheme that explicitly "does not guarantee the supply of electricity" - grid demand-response carve-outs can power you down [6]. Compass can terminate for convenience on 30 days' notice [4]. Delaware law governs; all hardware sales are final [2][3]. The new Easy Exit line is the honest escape hatch [1].
The status page is admirably public - and undermines the marketing: on our check it showed a North Dakota partial outage unresolved since September and several curtailment notices [7]. The self-reported scale figures (5.9 EH/s, 20 facilities, 160 MW) are identical to an August 2025 snapshot - stale [1]. The 2022 collapse that cost customer deposits is documented in contemporaneous press but appears nowhere on the operator's site [8]. Rates, marketplace commission and KYC policy remain unpublished [1].
The 2022 Oregon-facility collapse remains the defining event - lost deposits, a CEO resignation - and it was never acknowledged on the operator's own pages [6]. Since then: a new CEO (Paul Gosker), Texas expansion, the SpiderPool deal with its published 1% pool fee [9], and the Easy Exit relaunch [1]. Fresh operational friction: the Iowa (Hopkinton) 30 MW site's rezone was rejected in August 2026 over noise complaints, with a possible cease-and-desist pending [8], and the status page's unresolved North Dakota outage contradicts the uptime marketing [6]. Reddit pulse could not be verified this pass (mirror throttled); Trustpilot is blocked from datacenter IPs. The status page itself remains the best running record of facility friction [10].

No published $/kWh, commission or card fees - everything is quoted per order [1]. The only published fee datum is pool-side: the SpiderPool partnership offers Compass customers a 1% pool fee on FPPS - a 75% cut from the pool's standard 4% - which is the pool's fee, not a Compass commission [7]. The standard contract's real costs are the friction points: 3-year term, termination fee = remaining fees, storage-with-forfeiture [4][5]. Easy Exit trades those away for month-to-month flexibility [1]. KYC: marketplace sales require identity verification; general policy unpublished [1].
Compass is a real, scaled operator with the best product breadth in hosting - and the least published pricing among them [1]. The Easy Exit line fixes the worst clause in the standard agreement [1]; the standard agreement itself (forfeiture, UCC interest, no electricity guarantee) still deserves a lawyer's read before signing [4][5][6]. Watch status holds until rates are published and the Iowa situation resolves [8].

A real, operating provider can still lose you money: with a contract you own no hardware, revenue follows coin price and difficulty, and most published contracts are priced so the seller comes out ahead. "Legit" means the operator exists and pays what its terms promise - not that the deal is profitable. 15 dated sources back this page; they are listed under sources.
Same category, scored on the same criteria - so the comparison stays honest. Compare only in the same unit, and read the minimum, KYC and proof columns before switching.
