I'd sell of all my bitcoins in the event that the price spikes to something crazy in one day like the $30 spike, only to buy them back later. Anytime I try to do any day trading I lose out though.
I don't consider myself a crackpot. Austrian economics bother me; blow-hard libertarianism bothers me even more. I realize that the bitcoin "community" is ridiculed from time to time for being so viciously loyal to its namesake currency and its dream of global economic upheaval. Generally, I am cautious to associate myself with anything that emits a crackpot-esque vibe. Still, even after the ridiculous amount time I have spent on this forum, I have yet to discover any reason why bitcoin could necessarily not be the currency of our grandchildren. So thus far, I'm sold. And I'm here for the long haul.
I agree with the "crackpot-esque" bit. I don't buy into any of the hype that BTC will replace USD, or that USD will collapse anytime soon. I DO believe that bitcoin fills a gap in the Internet and has a ton of potential. I don't see any reason why BTC cannot exist side-by-side with USD for the next 100 years and I'm very excited about the possibilities for BTC.
