I do not come to hotcopper these days. It is really wasting time to see many unproductive comments.(if you know much about what is going on , you do not have to ask other people or check or argue with someone who do not know much) Much better spend time for studying.
If you spend time for studying instead of spending time for posting or checking these things you could have learned so much about oil mining. have a good day.

If there are buysers ,always sellers as well.
If all have the same idea, market does not work and you can not make money there.
