With light action, Spread is too wide to move a large block at 20 cents right now. If you need fast execution, you will likely attract nibblers if you offer your shares at 10 cents. JMHO Good Luck!
I'd split it into blocks of 2,000 each and vary your prices from .10 up to .40. Hopefully you'll get some cash you need that way, although the ATM fees are a little high.
