Earlier quoted context omitted.
You might working with an oversimplified model of the market. If you have 1% of all bitcoins, you're not going to be able to sell them all at the highest standing offer-to-buy (OTB). If the highest standing offer to buy is at $700, it's not going to be an offer to buy all 120,000 of your BTC. It might be an offer to buy 100BTC. So you sell 30BTC at $700 and then move on to the next lowest OTB, which might be 20BTC@$6…
heh so then how come when Bitcoiners are quoting the price of the ecosystem they always take the number of BTC * the highest standing OTB... i know thats kindof a tangent but.... seriously, i'm curious
How do you think an exchange rate between say USD->EUROS is decided? By the last trade price....
