This is what I posted a few weeks ago on educating people about bitcoin.

"Also, try to dissuade people from promoting Bitcoins from an investment angle, i.e. its potential returns. Viewing Bitcoins in terms of fiat is completely missing the point, and hence totally irrelevant.  BTC is a tool or an "enabler" for the people against the government and the banks. If serfs and slaves escape a life of indenture by fleeing into the sewers, you should lead them out of the sewer and into a better life, not by leading them back to the old world of enslavement!  Bitcoins is the ticket into the sewers and hopefully out of it into a better world.  By thinking BTC in terms of fiat, and how much fiat one can made, one is at risk to becoming like Cypher from the movie Matrix, i.e. wishing that he had never learned the truth and leave the Matrix (fiat world) in the first place. They will be the first to betray Bitcoins if given enough incentive by the fiat world ruler."

That being said, having a deflationary currency by design and periodic mass exposure by the media, first in 2011 and now in 2013, is going to cause huge volatility in BTC exchange rate as people rush in and out, hoard and dump, from time to time.
