I think I can explain what's happening with the price.
Some over-greedy people with low IQ moved almost all of their coins to places called MtGox and SilkRoad, where they could speculate freely and buy illegal stuff. Doing that, they ignored and defeated the most important part of bitcoin: decentralization and put into the hands of a few entities hundreds of thousands of coins (Mark, USMS etc)
The Silk Road and MtGox events are very important milestones in Bitcoin's history and personally I do hope that both Mark Karpeles and Ross William Ulbricht face at least 20+ years of jail time for their deeds. Their 'businesses' had good parts also and if we were in an ideal world, I would oppose jail time and put their asses to hard work, but since this is not possible, jail it is.
Their actions brought immense bad news over Bitcoin as a whole and stopped much of the adoption phase. We have also the 'speculators', which buy and sell bitcoins only for fiat profit (never ever forget that, it's all about $) - they help a lot to crash the price, which in turn brings bad bad news. There is a small fraction of speculators which try to make their BTC holdings bigger, but that's another matter.
While I do not wish for it to happen, because too many people would suffer, a global financial crysis would put Bitcoin right next to gold and silver and potentially make it a New World Currency. But that would be a forced adoption in my opinion and I'm pretty sure we'll see lots of tears from the people that heard, used, speculated, mined or stolen bitcoin and never understood what's it's purpose. I'm sure that each one of us will regret of having even 1 BTC and not putting it to storage for a long time.
As much as I hate having our beloved coin's image being tainted by that stuff, I can't help but feel that these black markets are actually helping BTC's cause. The auction of the seized coins was ultimately a good thing for BTC and the fact that these markets are actually using this currency in the way it's designed instead of hoarding it, is a dirty, but working "proof of concept" at the very least.
Yay for me, long time listener, first time caller. . I've been reading this forum for a long time now and I am long on BTC and have invested a signifiant proportion of my limited wealth. I'm currently torn as to weather to invest the lot and sell bits and pieces when I need cash. This would ensure that I'm well placed for the "moon" but hopefully can quickly change my position if things look seriously grim.
