In my holy opinion it's quite senseless to mine this coin now (or even later) as the rewards are getting bigger with higher block count.
I did some research and I guess it's another "experiment" of Til':
Genesis Block:

Quick search on github:

In conjunction with the (staking) premine I'm unsure about the future:

Then there are giveaways for miners on the unomp pool which makes it probably even uninteresting to mine on a regular pool as the
adresses are not visible there.
However, it's surely fun to mine this coin and do a bit trading when it hits YoBit ..
There are working pools already, so with all these things, I don't see the point in making another one...
