Very Good point. There are a ton of pump and dumps out there everyday, that people pump then leave the next day. The only pump here is good DD. I certainly would not risk my money on a p & d.
I will try to do more DD on the developments you speak of since the PPS is at bargin basement prices. Its really hard to find alot of independent confirmation about Sentinel and Pinnacle and I don't trust pinky CEO statements on just PRs alone.
