I got in at ~$2 and have taken the opportunity to average down.
I beleive they are real, I checked out the institution & funds that hold ~ 10% of the stock.
It's to common to see so many funds buy a small cap Nasdaq company.
The funds excellent acces to information.
BTW The largest USA Fund Black Rock increased their position from 2.4M to 4.6M
