Matter of fact, let's do just that for the heck of it, see how far we can go with it. I'll pick up a rock and call it Akorn and put it up for $10. I'll buy it back for $10 and let's see how much it'd be worth by the end of the year.
Sure, let's do it! Can you send your rock to my rock collection? Can you send a hundred rocks? How about a thousand?
(by the way, I live on the other side of the world)
