The top during a pump and dump is extremely important as we can look back at the volume during the initial pump and when those posting about how great of a investment GRNF is - just look at when they started posting - 09/11.
WOW, the entry cost on 9/11 was around $1.70 - damn near the top of the pump - those that entered that day are down 59%.
Now we know the reason several are trying others to invest - they are severely underwater. They believed the hype and have been crushed.
Still waiting for any of the Costello followers to post proof that he owns a weed bank - or that he manages a billion dollar hedge fund (that is hilarious).
