Yes. But at some point I believe they will uplist form the ASX to Nasdaq or another major exchange. The CEO has said, that he is considering the pros and cons and I have to admit that being on the ASX shields us from short attacks and manipulation. I think the uplist will happen when they are in a solid financial position to do it right. 1-2 years IMO.
Also, the reason for the low volume is that this stock is mostly held by longtimers and large holders who aren't selling. The real float is very insignificant and once there is a demand by new investors and institutions the won't be many shares up for sale. I have been her for +10 years and so have many others. +$20 might make me consider doing something with my trading position. But not before. And the long position is here to stay.
