Probably would not be a wise decision on your part. Everything that can be known about Bitcoin is readily available to anyone willing to do a little digging. If the CIA ever does set its sights on Bitcoin, they're sure as hell going to know it inside and out. And if some parts of your presentation turned out to have been a little misinformative... well, that would be a bit suspicious. I mean sure, present Bitcoin with the audience in mind, spin things their direction, but there's really only so much framing one can do when the whole picture's out in the open for all to see.
