I tried Kryptex in the last day, but there is not difference in terms of profit between it and winminer.

In the last days the winminer profit dropped over 50% and it seems the same for the other miners too. What can it be? XMR says too busy and ETN says no job from server.

I mean: I was able to mine XMR and ETN with several miners and each one of them was running at 2 usd per day. Now the same configuration with winminer produces 0.80 usd per day mining SUMO.

Same thing with Kryptex but I can't see which coin I am mining.
