We don't need mintpal to get JPC used and abused. Look at cryptometh and Recently ENC. You guys are sending JPC to its deathbed!!
I tend to agree... it seems like just a pile of day-traders, who essentially just run a coin up and down so much everyone gets tired of waiting for it to do anything else and leaves....
I have stopped even looking at coin data there... so getting JPC listed there doesn't excite me.
It has the volume to make a good coin successful though. A crap coin will fail, but even with the limited volume on bittrex it dipped to 40-50 and hung there nicely, so I think it will be fine on Mint. There is too big of a community built around it to not stabilize after a week or so on there.
