Please clarify what you mean by "cancelled account."
One possibility: Your broker should be able to liquidate your PTTN shares, and then you can book a tax loss (vs. tax gains) for tax-year 2019.
Or, you could spend ~ $ 130 for a crazy/stoopid OTC stop sign lotto ticket. Buy 1,248,000 shares @ .0001
Hold your 2 million shares for a future miracle/pump/2da'moon/larger tax loss, etc. !?$ :-D
