That just screams "bubble" to anyone who's seen one. Bear in mind that the Bitcoin system generates no revenue. All funds must come from new investors.
I felt like responding to thank you for making a thoughtful post, if for no other reason than you're predictably getting the broad dismissal from the bulls. I definitely agree with analysis of the fundamentals of the market, though one thing struck me as I visited your site:
We predicted the mortgage crisis in October 2004, again in 2006, again in 2007, and said it was here in March 2008.
This rather plays in to the criticism of many long term bears, in that it's said if you predict a big crash, correction or recession sooner or later you're bound to be right at some point and you can accept your 15 minutes of fame. Trying to act on those regular predictions can be much riskier though, as the classic quote goes "Markets can remain irrational a lot longer than you and I can remain solvent". Which isn't to say that I suggest speculating in bitcoins or participate in it myself, merely to suggest that bubbles are much easier to identify than to time. If you accept a rather straightforward analysis that there is no fundamental value represented by bitcoins and that it's entirely priced by speculation, then that suggests the bubble has been ongoing for quite some time and could easily hold out longer than the recent top might make it seem.
It's amusing watching the Bitcoin community flail around. Most of the classic financial disasters are being re-enacted in miniature. We have pyramid schemes, tulipomania, bucket shops, pump and dump... This would be fun if it were an MMORPG.
I agree that this makes the entire phenomenon fascinating. The communities openness to such transparent hucksterisms like the pyramid schemes seems to speak volumes about the main interests in bitcoins. And while I'm not schooled in such things, this also seems to be a rather unique twist on the pump in dump where there appears to be no central actor with the pumping actually done by all the market participants themselves through some kind of ad hoc understanding. It really feels to me like it's been taken hold at least in part by penny or otc manipulators. Very interesting to watch, seldom do you get such a raw view of it because of the legal implications. I just hope nobody is risking their retirement of college fund.
Cheers,
