Now Lets lower the market cap with 400mil!
139.382.267.410 - 400.000.000 = 138.982.267.410
[138.982.267.410] ÷ [16.923.950] = 8.212.16
So 400mil is literally only a small change of $ 23.64 in this huge market.
It doesn't work that way. The price is determined by supply and demand, which are
curves and not single values.
However, I agree that the Mt Gox sales were not a major factor, simply because the sales have stopped and yet the price has started to fall again.
Bitcoin market cap dropped couple billions, not 400 millions that is a big difference. Mt.gox inflicted on supply, but that is not over, many people, like always, will try to make fast profit, now they will dump bitcoin when ever they have opportunity for that. Market is going trough turbulence times, for some of us its all strange cause we didn`t expect this sale of from mt.gox, people should learn from this kind of events, and how something can inflict on price.
Mt.gox was one of the reasons why bitcoin price is dropping, but you have other reasons too, news about google, fud from China. Its never just one reason, its many of them, always.
