A clearly-identified, long-running Armenian operator with published prices and real infrastructure, but its cloud contracts are rigid, up to 60 months long, carry no hashrate proof, and only show returns through projections the buyer controls.

ECOS (ECOS-M) is an Armenian-operated cloud mining provider offering fixed-term Bitcoin mining contracts since 2017. It targets beginners with low entry prices and long-term commitments. While it operates under a registered entity with real infrastructure, there is no independent proof that purchased hashrate exists - returns rely on optimistic projections you control.
You can rent SHA-256 Bitcoin cloud mining contracts starting from $99, providing 21.9 TH/s for 360 days based on 2026-09-24 data. Longer contracts go up to 60 months (1830 days). ECOS also sells and rents physical ASICs. You do not own hardware with cloud contracts - only a right to daily BTC payouts as defined in the contract. No GPU or AI compute options are available.
Contracts are fixed-term, up to 1830 days (60 months), with no early termination or refund rights after activation. A daily service fee of $0.0332/TH/s is deducted from mined BTC, following a small prepaid credit. Payouts accrue daily to your ECOS balance; withdrawals require 0.001 BTC minimum and are not processed on weekends. Refunds are only possible if the contract wasn’t activated within 48 hours.
There is no independent proof that the hashrate you pay for actually exists. ECOS claims blockchain verification for marketplace ASICs and shows real-time stats, but offers no public pool worker or audited hashrate data. Operator statements alone are not verifiable proof - this remains a trust-based model with no external validation.
ECOS is a long-standing operator with a registered Armenian entity, data center at Hrazdan thermal plant, and coverage in trade press like Data Center Dynamics. However, the brand has been used in third-party scams, including a 2026 romance/pig-butchering scheme. Data quality is "reported," not verified, and conflicting info on minimum contracts raises caution. Reputation is mixed due to aggressive ROI marketing.
Cloud mining starts at $99 per contract (21.9 TH/s for 360 days), though the FAQ cites $149/$150 as minimum - creating confusion. ASIC purchases start at $1,299; rentals at $2,290. Payments accepted in BTC, ETH, USDT, and other major cryptos, plus fiat. KYC is required. The calculator shows high returns (up to 256%), but these depend on user-set BTC price forecasts, not guarantees.
ECOS offers a legitimate-looking cloud mining service with real infrastructure and transparent fees, but no verifiable proof of hashrate. Only consider it if you accept the risk of unprovable performance and rigid terms. For lower risk, compare with direct BTC purchase or provable hosted ASIC ownership.

Ready to try ECOS (ECOS-M)? Start small, verify one payout, and only scale up once the hashrate or compute actually matches what you paid for.
Based on our checks as of 2026-09-24: ECOS (ECOS-M) scores 4.6/10 in our weighted review. We logged 3 red flags (listed above). Facts are reported, not fully verified - test with a small purchase and a withdrawal first. User reports and operator background are documented with dated sources in the meta-review below.
You get a right to daily Bitcoin payouts based on a set hashrate for a fixed term. You do not own hardware - only a contractual promise from ECOS, which cannot be independently verified.
The upfront cost starts at $99. A daily service fee of $0.0332/TH/s is deducted from mined BTC. There is no refund after 48 hours, and no way to verify the hashrate is active.
The site advertises $99 as the minimum, but the FAQ states $149/$150 - creating inconsistency. No trial contracts are offered beyond the initial purchase.
Mined BTC accrues daily to your ECOS balance. You can withdraw once you reach 0.001 BTC, but withdrawals are not processed on weekends.
If ECOS stops operating, your contract becomes worthless. You have no claim to hardware or hashrate, and no refund rights after activation.
Buying BTC gives immediate ownership and price exposure without fees. Buying hardware lets you mine directly and verify output. ECOS contracts add counterparty risk and fees, with returns dependent on optimistic projections.
