Been mining MONA for 6 hours with 330MH/s... Mona value still 0.

The last Mona block was found 7 hours ago. Your shares will be paid out once the next block is found. Please take the time to read the FAQ.

Thanks for the quick reply! :)

i have been mining mona for about 5hrs with 18 1080-s at around ~600MHz nothing happened. But hardest part is the pool does not seem to show mature (unpaid) and immature balances, so there is no telling when, if it ever will be paid out on dashboard. Will there be an enhancement in the future to show it?

The pool does show paid balances under "MyStats" -> "Earned". Unpaid balances cannot be shown as they depend on the block reward, which is not known until the next block is found. If you need this you'd probably better off mining at a PPS pool - for much higher fees of course. The recent value drop of Monacoin and Vertcoin made many pools including ours suffer from dramatic hashrate losses due to miners shifting to more profitable options.
