The issue with $OPTI is that it's not even a good candidate shell for a new company to occupy (RM) in the future. The amount of auditing hours, legal hours, settlement of debt, unraveling of fraud, etc., isn't worth messing with by a long shot. Clean, stigma-free shells are readily available for companies looking to go public on the pinks - for a LOT cheaper than what it'd take to rehab a basket case like $OPTI. I believe the ticker will eventually - probably sooner than later, end up in the grey market where for practical purposes it can't be traded.
