Mining at miningpoolhub with 20x 1080ti. 18000Mh/s = 7900 dgb in the past 24 hours.
Difficulty jumps alot for dgb, and earnings (in dgb) varies a lot, much more than zcash or eth. I think it's because the total hash rate is lower, and in general folks who mine dgb tend to switch to more profitable coins more often, like HUSH now, or zencash a few days ago.
