Wow,  I have been away from this space for several months but have 8 x 280's mining Zec - my pool shows estimated earnings of 0.2 zec / month.  What on earth happened?  After a quick look around it appears that Zec allowed ASIC mining - that appears to have killed off my GPU mining profitability...  I am probably loosing 3-4 USD per day.

I have just shut down my miners for this reason - I will need to look for something else to mine.  Anyone have any advice?

Many thanks
