I'm a complete layman in this field - but looking at the oil price charts it seems that its never been lower. Even from production/export cost from various countries - it doesn't seem like this price can go on for prolonged periods. I.e. it seems to me that it has to go up...

Any experts here - would this be a sound assessment?

Also (again as a layman) - what would be a good way to bet on this? I.e. can I buy crude oil options virtually, hold them for 1-3 years and sell them as easily as I could stock online? What would be the best way to do this + any lowdowns (except that my bet might be wrong)?
