Bubble? Bitcoins are trading at the same price they were 2 weeks ago (at least it was last night, as I type this the price is already back up to $20...). I think this should be considered normal market volatility more than anything like a bubble burst.
I almost feel like "bubble" is now just a buzzword that was mentioned on the forums a few times and now all these people that know nothing about markets are repeating it ad nauseum.
I posted this topic after reading this article:
http://www.hightechforum.org/bitcoins-a-crypto-geek-ponzi-scheme/It concludes with the question "Can Bitcoin Survive After the Bubble Bursts?"
I was looking for some reasons on why there's more to Bitcoin than merely some speculative bubble that might someday burst; what is the intrinsic value within the Bitcoin currency that will stop it going to zero?
Personally, I think the sheer time and energy focussed on and invested in Bitcoin in mining and trading produces that intrinsic value, which forms a valid base for its value as a medium of exchange.
