Although I understand we've been having very good days lately, I've been around since a little before then. Considering the HUGE hashrate we have now compared to when I joined, I think that some of the balance isn't showing up. Yesterday, the graph shows quite a jump at a random point in the day, with a drop in unexchanged that does not equal the amount gained.
The "balance" we have right now is similar to what we'd get with ~2 GH/s before the days of DOGEs, I think. Not sure but the balance doesn't seem quite right. I think that something just isn't updating.
From what I gather, h20 is probably going insane with all the growth and work necessary to keep things running. He'll probably get around to fixing it at some point, if there's indeed a little bug. We'll probably see a huge spike here sometime if I'm right.
EDIT: Or, I guess we could be getting screwed over by bad luck or whatever else. Who knows, I guess.
