Another thing that I observe about this coin.
The more hash power that everyone use the higher the difficulty and longer it is to find a new block.
There was only one pool previously and we were finding a few block every min. And difficulty not that high as of now.
Now a second pool has updated their wallet and suddenly things move to a crawl, difficulty rises exponentially and time to find new block is longer.
While the difficulty and time of finding new block is swaying up and down but it seems with more hash power everyone is using the higher the difficulty it will reach.
Just an observation.
