This way miners will avoid the KAWPOW algorithm. On new video cards, this algorithm is not very profitable and consumes a lot of energy. The old video cards VEGA 64 and VEGA 56 perform quite well here at 30Mh/s, although the 4090 shows 65 Mh/s. And the 6600 XT is one of the most economical cards based on this algorithm.
Nexa draws less than ETHASH so I kind of like it. Also, making a profit now. Hope it lasts.
