What It Is

NBMiner is GPU mining software, not an exchange, wallet, or DeFi platform. The official website provides Windows and Linux downloads, along with changelogs for different versions, command-line parameters, API examples, and sample mining pool connection configurations. Its core use case is enabling users to connect NVIDIA/AMD GPUs to mining pools and mine PoW coins or algorithms such as ETH/ETC, RVN, BEAM, CFX, AE, and ERGO.

Core Features and Support

Based on the main documentation, NBMiner supports algorithms including ethash, etchash, kawpow, beamv3, octopus, cuckoo_ae, and ergo, and provides configuration examples for pools such as f2pool, NiceHash, 2miners, nanopool, herominers, and woolypooly. It supports backup mining pools, SSL connections, SOCKS5 proxy, REST API, Web Monitor, log output, temperature limits, power limits, core/memory clock settings, and fan control. For NVIDIA LHR GPUs, historical versions offered ETH/ETC mining unlock features and multiple LHR tuning modes.

Pricing and Fees

NBMiner’s business model is not based on subscriptions or trading fees, but on a developer fee. The official website lists a 1% fee for ethash/etchash, 2% for cuckoo_ae, kawpow, beamv3, and ergo, and 3% for octopus. The software allows users to adjust this via the --fee parameter; setting it to 0 can disable the dev fee, but will reduce hashrate. If not disabled, the actual fee will not be lower than the default rate.

Pros and Cons

Its strengths are a complete feature set and broad algorithm coverage, making it suitable for mining farms that need fine-grained configuration. The API, logs, backup pools, SSL support, and temperature-control mechanisms are also helpful for long-term operation. The downsides are that command-line usage has a relatively high learning curve, and the software has clear dependencies on driver versions, VRAM capacity, and GPU models. The official website does not disclose the company entity, location, licenses, insurance, or customer support SLA. It is also worth noting that ETH no longer uses PoW mining, so the related ETH features are mostly of historical relevance.

Who It’s For and Access from China

NBMiner is better suited to users with GPU mining experience who can configure mining pools and wallet addresses on their own. It is not suitable for beginners who want to buy and sell coins, deposit fiat currency, or use a custodial wallet. Access from China is not described in the main documentation, and mining plus related network connections may be affected by local policies, mining pool connectivity, and the payment environment. If you need alternatives, you can compare it with lolMiner, T-Rex Miner, GMiner, TeamRedMiner, and similar tools.
