These stocks close in 6 months time (1 jan 2016).
Bitcoin went below $300US at the beginning of the year . It had been dropping since a high of about $1000 in November 2003. It has been discovered that the sharp rise to that $1000 was due to manipulation in the biggest exchange at that time (MT GOX). So it was always going to come way down but nobody had any idea where the new "bottom' might be.
By July 2014 it was $600 and then it went steadily but evenly down to $313 by 1 jan 2015.
Then it went for a sudden dive and was for a brief time (hours) $177 on 14 January 2015.. It went back to over $200 shortly thereafter and every since has traded in the $200-$300 range.
The early adopters of bitcoin are big players in this. They got their bitcoins cheap (eg for a few cents or a few dollars) and much of the talk on bitcoin forums was the impact they and others were having it buying bitcoin at the $220 type level to stop it falling further.
It has recently gone up from this level (is now about $250) but there has not been anything special ( new news, changes to adoption levels etc) that would 'explain' the rise. But bitcoin is highly speculated so rises and falls come and go more often than many other commodities/currencies.
So what do you need to look out for in the next 6 months that could really affect the price ie make it go outside the bounds of $100-$500?
1. what happens in China - ( the Chinese are big speculators, big miners (ie creaters of bitcoin), run many of the biggest exchanges and have a government that intervenes directly on some issues)
2. when some one off events happen that may happen before 1 jan 2016 including being able to buy properly regulated shares in the US in the movement of bitcoin via the ETF by the Winklevoss twins ie people and especially pension funds can get exposure to bitcoin without the risk of actually owning it
Happy to answer any questions anyone may have.
