I dont know what rig you would have, but you need at least 700 bux for a computer and card that will mine bitcoins well.  At 2 dollars a bitcoin, minus your electricity, it will take you a long long long time to just break even and pay for the rig.  That is why I see it at 10 to 15 bux a bitcoin being a good price, and a wall between 10 to 15 for stability for businesses to take the risk in selling items we need for bitcoins.  As it is now, I agree the stability is the biggest issue.  I do not think 10 dollars a bitcoin is too high for a normal rig to create bitcoins and make sense.  Takes about 3 days to make one bitcoin, thats about 20 bux a month generating bitcoins with a 700 dollar rig, minus the cost of electricity, so do the math holy hell over 3 years to pay for your mining rig easliy.  That just doesnt make sense.  This is where I see it needing to be around 10 bux to 15 a coin and a stable wall built as a guarantee for businesses to take the risk of selling items for bitcoins.  No real business is going to sell anything that matters for over 10 bux, that might be bought for 5 bitcoins, when 2 weeks later those 5 bitcoins would be worth 5 bux, too risky especially when you start selling items like ipods, ipads, computers, graphics cards etc, things that cost 100s of dollars, way too high of a risk unless you convert your bitcoins into cash immediately, which if your doing that then whast the point, just sell them for cash to start with
