Warning!!! Your coin can die!!!
Now:
NetHash: 121.2Gh/s
Difficulty: 61919 !!!! (Very high for current NetHash 121.2Gh/s)
With current diff and NetHash total block in a day: 37 blocks/day (transactions very very slow, small profit)
Current block: 256 099
Next Difficulty retargets on block: 258048
Now need 1949 block for retargets diff!!!
Now need 1949/37 = 25 days!!! for Difficulty retargets !!!!! - This die you coin!!!
Now mining profit you coin less than $0.9 a day from GTX 1080!!! -> this will reduce NetHash -> this will reduce blocks/day -> this will increase days for Difficulty retargets
this will reduce mining profit -> this will reduce NetHash -> this will reduce mining profit -> it'll kill the coin!!!!
You can change it.
You need Hardfork: need change Difficulty retargets more often or using Dark Gravity Wave.
