this is nothing! 5 x , I mean watch for two digit % increase (in difficulty) seems dev has not released his 3% and could have done so already

every moment now you risking mining less and less with more $ into rental gear which what people do, I say if dev does not realease premine you should see 2 digit % increase soon

+ decreasing reward ratio, checking table again on page 1, coin btw in my best estimation might reach 1 $ FIAT a unit and go from there all depends on you
