Then Penguin came, and it wasn't. 80% of my G traffic disappeared,
When you started your website did you rank and have lots of traffic?
If you lost 80% of your traffic you probably lost 80% of your backlinks and you could say you moved 80% back in time when you didn't have as many links, ranks, and all that comes with it as you did when you got nailed.
You CANNOT really recover from PENGUIN... chances are you haven't done any link development since you got nailed and that is the cause of your non-recovery.
Google through PENGUIN removed your ability to use inorganic links so all you can do is "make your website great!" But if you aren't investing in something that generates "BUZZ" on your domain... you will be like a domain that never started doing link development at all... and since there is no buzz either... they just don't rank.
