But, as-you-say, you didn't-come-in until BK was imminent.
I day-traded it for a profit a few times under $10 and averaged-down at $2 and $1 counting my money toward the day when it recovered.
I bought only once post-BK and I read of large bankruptcies that spared pre-BK shares. I'm betting $1000 on it but I'll be pleasantly surprised if it materializes. (NOT a good trading strategy! lol)
