If we are not yet in a bubble we'll be there pretty soon.  It's kind of inevitable - bitcoin is just such a good story, it's the ultimate spreadable story  (http://www.henryjenkins.org/2009/02/if_it_doesnt_spread_its_dead_p.html, http://www.henryjenkins.org/2009/04/how_sarah_spread_and_what_it_m.html, http://www.niemanlab.org/2010/11/why-spreadable-doesnt-equal-viral-a-conversation-with-henry-jenkins/).  All new, good technology generate bubbles, Gutenberg eventually got bankrupt and with the internet in general we've seen it not that far ago.  In a way it is not all that bad - it will bring money, recognition and new businesses - all this should eventually smooth all the rough edges of the current technology which is not too attractive to anyone beside hardcore geeks.  Some investors will go bust - but if the business starts using bitcoins for daily stuff - then this should stay.  It's only after the first bubble crash that we'll gain good understanding of what kind of economy bitcoin brings in.

What are your views on the first crash?  When will it happen?  What would be the price of bitcoin after the crash?  What is your strategy to survive it?
