not my first time, i traded it in 2011 and in 2013 and again last night. Lost a lot of money in it, but i keep coming back. guess i'm a glutton for punishment.
i saw it dropped 20% after earnings was released last night, so i grabbed a small amount 1800 shares at 2.68. Right now it's at 2.92 so it looks like it was a good gamble and scalp trade.
I've never traded any other miners. I mostly trade small cap biotechs, but I'm not good enough to give advice either way. Good luck
