I don't expect to ever get my investment in PTSC back, given the measly 100 shares I own of CPMV (which I can't get rid of - I've tried!) in return for the 25,000 shares of PTSC I used to have, but I still follow the story, which today is:
Average daily volume: 360
Volume today, 19 July 23: 11,511
Wow!
