The Rigel Nvidia GPU is a newcomer on the mining software front and apparently is less than two months old since its initial release, supports just a few crypto algorithms, but looks nice with it the terminal user interface it provides. We haven’t used it up until now, but it has attracted our attention with the addition of support for the nexapow algorithm used by the NEXA project that is lately ginning quite a lot of attention among miners and crypto traders. The Nexapow mining supports comes with a 2% developer fee, but it is apparently well worth it as the miner manages to bring up the hashrate on average about 10% in our quick tests compared to the performance that the previous best performer BzMiner manages to get you at the moment. Both BzMiner and the Rigel miner do only support Nvidia GPUs for mining NEXA, if you want to mine it on AMD GPUs you need to stick the third option which is WildRig Multi that supports AMD and Nvidia GPUs for mining NEXA.
At the moment the Rigel GPU miner is available for both Windows and Linux operating systems, supports only Nvidia video cards and supports mining of etchash (
