If you can make your money back and possibly more, God bless you! Just don't be the last person holding shares.
As for my "buddy", we actually disagree more than we agree. And, as he states many times, don't trust anyone on the internet, even him. I don't. Having said that, I do appreciate the class 101 he shared with me a few years back on trading precious metals. Gave me a great foundation to use in building my research on miners.
