The said part is JPC is also going down the drain.

Look at every other coin as well... All alt coins except for the random pump and dump coin of the day have been going downhill this last couple weeks. Even with my above average hash rate(although still not great) barely any coins are profitable to mine anymore.
The volume will return though, this is how markets work. Ups, downs, low volume, high volume, etc.
I think if we get jpc to go down to under 10, we might be able to flush out all the people that have been dumping daily no matter what the price is.
JPC has been doing exceptionally well compared to most other coins in terms of sustaining a decent price. Most go up massively and then crash down to the lowest of low within a day or two and then don't go back up for weeks until someone decides to pump it.
