That's just the story of any bubble. Lots of people will bid it up because they expect other people to join in, until at some point they stop believing others will join in. I can't disprove it, because bubbles do of course happen, but that doesn't say much about how long this particular one will continue. I guess what I'd encourage you to do is write some notes for yourself about exactly what you expect will happen, so that when the justifications for the bubble change again you'll be able to notice and hopefully get out in time.
