What do you think the bottom price is? 19? Last year you thought it would be $30, two years ago $35, and three years ago $40. What do you think you will think next year? If the trend continues (and why should it not continue??) you will think it's 10. I just think what you think, but I think it faster! Haha
I don't think I know what the bottom price is, nor do I advise others I know, unlike you. If you believe you know what the bottom is, why buy above it? I agree I see no reason why the trend would change at this stage.
