Turning 10k into 100K

Hey all,

I’ve made some good profit going from 5k to 10k. I’ve invested in penny stocks (Cei, HYMC, MULN) not that I’m on 10k I’m trying to find a strategy whereby I can turn this 10k into 100k. I’m trying to find stocks that can do this within a year or so. This isn’t my retirement money, I have a retirement portfolio that I do not touch. So this money I’m more willing to be risky. Currently I’m invested in NILE. But would like to decent advice in what strategy or perhaps what kind of stocks can turn this 10k into 100k within a year. Thank you!
