how many times must this be said on the forum before people will get it?
Until you will try to understand the psychology of miners. The price is related to the costs through the miner's expectations.
Well, yeah. BTC price affects mining cost, so people leave turn on or off their rigs until the difficulty balances.
Or they don't, and someone eats a loss they didn't have to eat.
Either way, that doesn't mean that the reverse is true; the only effect miners have on the sell price is to slightly increase or decrease the sell pressure based on their need to "cash in". Miners "needing to make twice as much" won't have a speck of influence on the
bid support - the price people are willing to pay for their BTC - which is where the $2 floor came from.
I want to see someone with $100M guarantee to buy Bitcoins at $4.50/each forever. I wonder what sort of confidence would be given if such a guarantee was in place?
Price floors have their own disadvantages.
Such as?
On second thought, I suppose most of the usual side effects are negated by it coming out of the pocket of someone with cash in hand. I suppose the main downsides are to that guy: he's spending a fortune on BTC, and will probably only be able to
a fraction of them without undoing his hard work (or ending up selling them back to himself).
