Really looks like a promising project. I love the current ROI of a MN ^_^
what is the current ROI ?
is there instant mining pool without need to wait 3 hours ?
As far as I know, you'll always have to wait until the blocks you helped to solve are confirmed to get something from the pool your mining at. As for the ROI, it's 1945.09% (according to mnrank.com). It will lower with time of course : The more MNs are on the network, the more you'll have to wait for getting a MN reward.
