Not OP, but it makes sense. A lot of investors hear about an asset going up and they want to join the party. A lot of the other investors try to predict where the emotional investors will go and buy the asset in anticipation.
Yes, that certainly can happen. But when that kind of speculation has a significant effect it's called a bubble, and is an exception to the usual rule that increased demand causes prices to increase up to a new equilibrium point and no further. Is there any reason to think that a bubble would occur in this particular situation?
