It's been on my watchlist, (same with RJDG) but have only done very surface DD on both.
Only OTC im in right now are AMFE (overwhelming majority) VPOR (kind of boring, but i think potential longer term, waiting to see how the sales play out, will take a year though) and previously mentioned BVTK, the most insane circus ever conceived. Lol
I did dump 5 mil BVTK today to take out original investment, all profit riding now holding 8 mil shares, so I'm much more comfortable circus watching mode now :)
Until either BVTK or VPOR does something different, I'll be tapped in the OTC for now. Though, if either go, I'll still end up buying more AMFE with most of it! lol
