Reason some people are selling PTSC could be that they are getting margin calls on some of the other stocks in their portfolios. This could cause them to have to liquidate non margined stocks to raise cash. Market is dropping and borrowing is tightening. Years ago in my youth, I had a stock go from pennies to $60.+ The whole time it was going up I kept buying, went on margin and when the stock crashed, I got destroyed. I'm smarted now. LOL  Hang in there and be very careful of margin. Remember, pigs get fat and hogs get slaughtered. Lets hope we will all be happy pigs soon. Doc
