Anyway I only know that if it goes too low miners turn their machines off. So no new bitcoins. Then price will go up.
Since difficulty grows up fast due asics I expect price to raise violently in next 2-3 months.
There will always be new bitcoins even if just one person is running their USB miner... Well they do have to sell them...
Dunno bout difficult raising violently, for that to happen highly powerful and efficient miners will have to come out. There are a lot of pre-orders waiting and the china dragon 1TH miner available now but these aren't revolutionary and won't be as effective as the first wave or 2 asis which caused the massive diff jumps. Most miners are now mining at a loss due to btc price, though I suspect the price isn't so low to turn off miners, but they will be more likely to hold if they can.
Even if miners keep cryptos the result is the same.
As I said in these situation who holds wins.
Cheers
