I had a friend I told about this and he invested and ended up cashing out at a loss... I haven't recomended a stock since... However when I initially bought in this stock was trading at .0008 & .0009 years ago so I guess when I first bought in I timed it right... It's the selling part I haven't been able to figure out how to do lol.
