If you can get anything above 0.20, I'd sell right away - from 0.56, that isn't too painful (frankly, anything higher than 0.20 would surprise)...the next 'run' will likely be from 0.005 to 0.02. This has been totally exposed as fraud now - the companies involved in the PR's have replied (to me and Sykes at least) that they hadn't even heard of the company until it was bought to their attention (thus the forced retraction) - the university does not exist, the PR's are recycled word for word from a scam company from a few years ago. The game is over - anyone still positive is either clueless and has no right to be trading, or hasn't yet received their promo shares and needs one last pump.
You can get out easy as SEC may not get here for days or weeks, but when they halt it like it did with SLJB, expect to get a penny for it, IF it even opens again. Punishment is likely much swifter when an OTC scams the SEC...at least with Pinks, they know they are all scams!
