Sazmining
You buy a serial-numbered BTC miner outright; Sazmining hosts it, bills power at cost and takes 15% only on Bitcoin actually mined.
not operating: bitriver.com NXDOMAIN, bitriver.ru = nginx placeholder, Telegram inactive since Dec 2025, zero news since Jul 2026 (founder detained on fraud charges per The Block 2026-07-30); OFAC designation (RUSSIA-EO14024, designated 2022-04-20) still active per SDN list 2026-09-30. Collapse, not scam.

BitRiver was one of Russia’s largest Bitcoin mining colocation providers, founded in 2017 and once claiming 300+ MW of capacity. As of 2026, it is in active collapse: its founder is jailed, the parent company is bankrupt, and the website serves no operational content. You should not rent infrastructure from BitRiver - it represents extreme counterparty risk.
BitRiver offered SHA-256 Bitcoin mining hosting, primarily for ASICs, under fixed-term colocation contracts. You would send your hardware to their Russian data centres and pay for power and maintenance. You do not own the infrastructure, and as of 2026, no new contracts are verifiably available. The service no longer appears to be operational.
Contract terms are no longer accessible: the official site serves only a default nginx page, and no public documentation outlines term length, maintenance fees, or payout structures. Refund policies are unknown, and there is no evidence of active customer support. Given the bankruptcy and legal actions, any existing contracts are likely unenforceable.
There is no verifiable proof of hashrate, uptime, or capacity. Historical claims of 99.93% uptime and 300+ MW were self-reported with no third-party audit. No public pool workers, on-chain attestations, or proof-of-hosting mechanisms were ever published. The lack of transparency means you cannot independently verify performance or legitimacy.
BitRiver’s operator, Fox Group, is in bankruptcy with ~$9.2M in debt, and CEO Igor Runets is in pre-trial detention over alleged $12.5M in fraud. The company has faced lawsuits, US Treasury sanctions since 2022, and loss of key partnerships. Reddit and news outlets like CoinTelegraph and Bitcoin.com confirm its operational collapse. Facts are based on public reports, not verified operator data.
Pricing is unknown and unverifiable. BitRiver historically charged per kWh, but no current rates are published, and the website no longer functions. Minimum purchase, payment methods, and KYC requirements are all unconfirmed. Given the company’s status, any prepayment would carry total risk of loss.
Do not use BitRiver. The operator is in legal and financial collapse, with no functioning website or customer access. For Bitcoin mining hosting, consider audited, transparent providers with verifiable uptime and clear terms. BitRiver is a cautionary case of centralized, unaccountable infrastructure.

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. 6 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.
You buy a serial-numbered BTC miner outright; Sazmining hosts it, bills power at cost and takes 15% only on Bitcoin actually mined.
Polish GPU mining OS (SMOS, $2/rig/month prepaid) plus SimplePod.ai GPU cloud; not an ASIC host despite the name.
US ASIC hosting from $0.0750/kWh (1 MW+) with a one-time $100 setup fee and a live ASIC marketplace; Indiana, founded 2022.
Flat $225/machine/month all-inclusive Bitcoin hosting in six self-owned Oregon sites; customer owns the ASIC and keeps 100% of BTC.
You would have received colocation for your ASICs in Russia, paying for power and maintenance. As of 2026, no services are available, and you get nothing - the company is defunct.
Unknown. Historical pricing was per kWh, but no current or verifiable rates exist. Maintenance fees, contracts, and terms are no longer published or accessible.
No information is available. The website is offline, and no trials or small purchases are advertised. Given the company’s status, no onboarding is likely possible.
Payouts were not applicable - you owned the hardware and mined directly to your wallet. BitRiver only provided power and hosting; mining rewards went to you, assuming the service operated.
No. There is no proof of operation, audits, or transparency. The founder is jailed, the company is bankrupt, and the site is down - strong indicators of a defunct, high-risk entity.
It already has. With bankruptcy, seized assets, and no operational site, your hardware (if hosted) could be inaccessible, and contracts unenforceable. Prepaid fees would likely be unrecoverable.
Buying Bitcoin or ASICs yourself gives full control. BitRiver offered no upside - only counterparty risk. With its collapse, direct ownership is vastly safer and more transparent.
