This is exactly the sort of discussion I wanted to start.
I do think price drives difficulty, but I believe there is a small impact of difficulty on price.
If difficulty is moved by price, then what caused difficulty to increase before there were Bitcoin exchanges?
I'm glad someone said this, because this is essentially the point I wanted to get to. Even if Bitcoin was unprofitable for everyone, there would still be people mining it. Just look at the alternate cryptocurrencies forum if you don't believe that people are willing to mine at a loss.
While I haven't mined at a loss, it has been clear to me that some people have. If demand for Bitcoin ever exceeds 7200 btc/day, the price has to increase, even if the people who are mining at profitability sell immediately.
Additionally, what would you, as a miner, do if Bitcoin was $.01 tomorrow?
I would and can buy every single Bitcoin at that price (and far higher). This is the miner's incentive, to get the coin at the rates that make his profitability worthwhile.
I'm going to stop responding now, but in addition to my purchase at $.85 prior to the latest increase, I recently made a 500+ Bitcoin purchase at exactly $2.01, compared to a several-month running low of $1.99 or whatever.
Ask yourself how the hell someone without a degree in economics does something like this? On November 14th, the person driving the price of Bitcoin down lost control. This is hugely significant, but no one talks about it. The new control-holder now seems have a surplus of BTC, and they need the price to increase. This is all a game of supply vs. demand, and risk vs. reward. In the future, when it is evident that $2.01 is never going to be seen again, people are going to be asking us, the early adopters, why it is that we knew what to do, and it is important that we learn that difficulty does, in fact, have a slight impact on price due to the conditions surrounding *why* the difficulty stabilizes, and that the impact these conditions have, *accumulates* the longer the price stays low and miners are mining unprofitably.
Anyway, I just wanted to end on a note that reiterates the point that we should help those individuals who want it within present leadership, because if we don't, they will probably start wars with each other. I'd really, really, like to avoid that. I think we can get the public to lend us their faith, and, in turn, so will the politicians and bankers. We just have to be cordial and supportive. We are technical geeks, after all, we don't really have any grand aspirations.
We just want to see our fellow man, happy, right?
I'll admit, this post is going to make virtually no sense today, December 8th, 2011. But people looking back on this are going to seriously WTF over it. I have to believe that there are technical and econ nerds/geeks like myself that understand the nature of what is going on.
