But in the meantime, there is money to be made in holding on to it. Look at AMZN speculation like Bitcoin speculation: there's really no intrinsic value of a Bitcoin or AMZN share, except that others want them and there's a finite supply of them, and also there is some underlying (quickly growing) market that they represent, which means that the shares should also grow in value.

Couple that with a nice PR machine ( can't understate the value of people like PMarca writing about how amazing they are ) and you've got a way to reliably grow your portfolio.
