Why NBminer?

NBminer Is a closed source NVIDIA and AMD GPU Miner for ETH, RVN, GRIN, BEAM, CFX, AE, SERO, ERGO for Nvidia CUDA and now AMD, which is available for both Windows operating systems. Has built-in support for backup pool configuration as well as support for SSL connections to mining pools. The program supports Nvidia and AMD and is often the leader in hash rates on various mining algorithms.

NBminer is the ability not only to mine Grin, but also the ability to mine in dual mode, Ethereum cryptocurrencies (PoW Ethash algorithm), as well as Bytom coins. It should be noted that double mining, due to the emergence of ASICs for many previously profitable algorithms, as well as due to a significant drop in cryptocurrency prices, has long lost its popularity. Most of the coins that were previously mined in dual using the Claymore dual miner (for example, Siacoin, Decred) now have such a complexity of mining that using video cards for this makes sense only for heating rooms or indirect heating boilers.


This commission usually does not exceed a few percent and is used by us to maintain and improve its work, as well as to add new functions. The commission is taken due to the fact that the program mines a short period of time (usually no more than a minute) every hour to the developer’s wallet.
