That's not how it works. Look at UPLMQ (now UPL). Commons in UPLMQ received a stake in the new UPL, probably something similar to 20%. The 80% loss that you are imagining is offset by losing the Q symbol and returning from the OTCs to the Nasdaq.
I have no position here. I don't know enough about the company to be bullish or bearish. But just wanted to clear up that point. Commons getting a 20% stake is a pretty good deal as far as bankruptcy proceedings go. More often than not, commons are completely wiped out.
