Wonder why there's still such few miners on the network even after the exchange listing, at the current price it is profitable to mine 
Yeah you are right!
mining is very profitable, but it is not listed on any profit calulators around. So many miners will miss it.

Yup, Dallar & DigitalPrice exchange isn't known to many people & definitely not listed on any mining calculator sites, yet. We still have some time to mine in peace before it levels out
