RAP Overview

Hello, this may be a bit late to this forum and I understand that there are many discussion threads with respect to RAP however I bought RAP back in 2016, and have been holding for a very long time, mostly to my detriment. Due to the journey in "emotions" with respect to this stock I've chosen to largely ignore it in my portfolio. Can anyone tell me if its still a hold and if there is still "great hope" for this stock, if so, how soon can it be commercialised to generate profit? or in the alternative, be bought out?

I understand this is all speculative but would be great if anyone was willing to give me an overview.
