In the next update of Gminer 1.87, the possibility of mining with AMD video cards based on the Blake2S or Kadena algorithm is added. For mining, AMD video cards with 4Gb video memory are suitable. The hashrate of RX480 / RX580 video cards is 390-420Mh/s with an energy consumption of about 100W. This miner also supports dual mining ETH + KDA, but so far only for Nvidia video cards. The commission for using Gminer on the Blake2s algorithm is 2%. You can download the miner on GitHub.
