I think Espers might be the best opportunity atm for potentially huge gains. Made a post about that one on my blog here and hope more people get on it and maybe send some tips my way once we reach the moon:) A safer bet which could still pay off very well I think is SAFEX (or SEC as it's listed as on Bittrex). Have started to move but still cheap (at 215 sat now). It's dev is former Maidsafe guy and it's looking interesting, check their website.
