Here is how I see it. The Bitcoin community is trying to decide whether Bitcoin should be a DAC (decentralized autonomous corporation) or a DAC (decentralized anonymous currency).
These are two different evolutionary trajectories, and they have impact on the Bitcoin price. The Bitcoin XT side seems to want Bitcoin to achieve mainstream adoption, and if you're thinking of Bitcoin as a DAC (decentralized autonomous corporation) then you care about the share price, or the Bitcoin price.
Bitcoin XT supports greater levels of adoption, which means a higher potential Bitcoin price for token holders. If you're invested in Counterparty, Omni, or similar projects which build on top of Bitcoin then Bitcoin XT raising the blocksize is critical so that you can use Bitcoin as more than just a currency. Wall Street has moved in, and Bitcoin XT is the chain that Wall Street will favor because they want to see the Bitcoin price rise over time, which is why there are ETFs being set up so people can buy Bitcoin as if it is a stock and use their life savings to do it. You also have Coinbase and Circle which are set up to bring Bitcoin to the mainstream, all of this will boost the Bitcoin price which means Bitcoin is more likely to be treated as a commodity or stock than a currency.
On the Bitcoin Core side the Bitcoin price is irrelevant. Bitcoin is just to be the DAC (decentralized anonymous currency), to be used by activists. Bitcoin Core is focused more on making sure Bitcoin stays anonymous, and that the particular kind of decentralization supports Bitcoin use for activists, not for Wall Street, not for the mainstream. At the same time Bitcoin Core don't seem to be thinking about Bitcoin as a DAC decentralized autonomous corporation, so whether it ever achieves mainstream adoption is irrelevant as long as it provides utility to activists, and as long as it is anonymous.
These are two different world views and the Bitcoin price is mainly at $200 because people believe Bitcoin is like a stock. Once people believe Bitcoin isn't like a stock, and that Bitcoin is not a DAC (decentralized autonomous corporation), then the price even at $200 might be inflated and we could be back in the $90-100 range.
If Bitcoin is to be a decentralized autonomous corporation as you see here:
http://coinwiki.info/en/Decentralized_autonomous_corporationThen Bitcoin share prices have dropped, shareholders are concerned, and these shareholders control the majority of the money and through that they control the future price of Bitcoin.
If Bitcoin is a decentralized anonymous currency, then Bitcoin has to improve it's privacy features, and shake off the Wall Street profiteers, the businesses around Bitcoin who want to take it to the mainstream, because for the most part if it is to be an effective activist currency, none of that mainstream Wall Street NASDAQ stuff is going to matter. At the same time, activists usually don't have any money so you shouldn't expect the Bitcoin price to rise very high as an activist currency.
Who will control the fate of Bitcoin? Will it be the shareholders or will it be the core developers? These are two different constituencies. Miners also have the ultimate choice because they have to choose the chain, but will miners choose the chain where Bitcoin price can rise dramatically or will miners choose the chain where Bitcoin price stays flat? Since most of us here aren't miners, it's for the miners to ultimately decide which vision for Bitcoin they prefer.
