$PBGC is being promoted by 12 different promoters, and with the price action it's what we'd call a pump and dump. So currently it's in the dumping phase. If you want my honest advice, your best chance of walking away with as minimal of a loss as possible, take what powder you got and wait for a bottom to form on the chart and then buy more shares at the bottom so that when it bounces you'll be able to average out your gains/losses.
Jump ship and realize major loss, or buy a ton more and average down. Just wait til ticker turns north to do so should you decide to buy more.
Im in simular boat, I have averaged down to where if it bleeps Im even or better. Easy to pick up a ton of shares down here. Should it drop another 50% Il buy again.
