With stocks such as this, one is safe in presuming "billions". It's not about how many shares there are, anyway, it's about how fast whatever amount there are can be churned to give the appearance of "something going on", as is happening right now, you'll notice.
It's simple, really: it's now TSRI's turn in the StinkyPinkyHypaPumpADumpAScamARama Machine and The Perps behind this P&D are going to play it for whatever they can get out of it.
Dump when they do.
