Are we selling MSTY? I dont know what I'm doing

OK, so I put 70k into MSTY at 15 bucks. Ive gotten some dividents, I can loss harvest, but I have no idea what I'm doing. I should stop reading reddit because I have no lambo and lots of regret over the last 7 or so years.

Am I holding this still or do I need to get out? I don't even know what a MSTY is. I am that regarded.
