We are mining expanse getting up to 60mhs, It's the most profitable for now, Zec earnings are lower on 330Hs and the price of zec is volatile...

That is right. but with the Claymore miner, it is better to mine ZEC now.

Hmm, zec dropped 30% so it doesn't matter if you mine Eth/Exp/Zec right now, earning are similliar I think...

They are similar. But for 7990, it is still a bit more profitable to mine ZEC.

Now it's monero Grin

Monero is very good coin to mine now.

7990 is better for ZEC.

The Eth file size is too larger now, it is not good for 7990.
