If it wasnt AMHL then it was one of the CD Holders. They are the only ones that would fork over 100k for a PROMO. Might explain why MAXM has been dumping so many shares as of late.
Paid promos like that always say paid by third parties but pretty much all involve offshore companies set up by toxic funders and promoters. While a company will deny knowledge of the paid promotion most know about them.
I will dig around more to see who is behind it - but offshore companies a bit more difficult to track down. Guess that jump to a penny makes more sense now given it was during the paid promo time.
