I quick guess is that once it reaches it's highest point that it's going get for a long while, then it might halve in price after that. So if it's not going to get higher than $3000 then I guess we could see $1500 again at some point. However, $3000 might not be the highest point it gets ... if the eventually top were to be $5000 then I think the low point after that could be $2500. In other words, I don't really know at the moment :)
