At very low levels historically. Long term monthly chart looks very good. Did a little research on it last night, is predicted to be more used in the future, overtake coal, so has staying power, not going away. Good time to start getting in? Am worried it might go negative. Seems like a good chance to make 100% profit in next year or two, if don't get killed by negative price. How would you trade this if you were in it for the long term?
