If it's all or nothing, then no, I wouldn't. I don't need the money right now so I'd let it build.
But yeah, I guess the thing is to cost average out, a little each week, as Khal is constantly saying. When it's down cost average in, and when it's up cost average out. That way we can enjoy some profits at $10, and keep enjoying them as it goes up. You're right—that would be a very good problem to have!
