I edited my long post several times so if you read it more than 5 minutes ago I have added some more thoughts.
Not sure holding on is a great strategy. I guess if you wait long enough the pump will sucker in new and less experienced people looking for easy money (like I was) and the pps will head back up. But no guarantee on that as many of these waste away to virtually nothing and basically dry up. The pumpers will use a story as long as it works and weave beleiveable twists into their tale. Eventually they start afresh and do it again and again and again.
Can others chime in and help Boundas out? I think he would appreciate more opinions than just mine.
