It is slow because the coin has been designed by the Dev to be hostile in resistance to rise and fall style miners and Multipools.
A steady global hashrate which should eventually happen overtime will see the blocks become more consistent.
I do have to point out that 7 mins per block is quite long but it helps to increase security against mining based attacks.
I for one think this coin is a breath of fresh air and for once we have a coin released with no pre-mine, no ICO or IPO rubbish.
This is just a straight up coin release and then mine away until it moves to POS with 3% interest which is a sensible amount.
It seems to me that this Dev has spent a decent amount of time thinking at least the development area of this coin out and it should pay off.
I will be investing once it gets on a decent and secure enough exchange.
This coin will need services though. (I can help with this if needed.)
