Protagenic Therapeutics Inc. (PTIX)

[Investstocks]

So this stock is down and supposed to be on bankruptcy.
I got some questions for the people who really know about finance.

If the company is in bankruptcy how can there still be a large increase in volume like that bringing the price up? didn't they get unlisted? I thought no one could trade this stock anymore. Thought whoever has shares is stuck with it and no one else could buy in.

So my final though is ATRNQ could actually break through and bring in some profits?
We could see the price going back up to $1 or more in less than 6 months?

thanks
