How can a stock with 14,000btc in dividends (and likely to decrease due to increasing value of btc) be worth 1,000,000 btc or about 1/10th of all bitcoins.

Simply ridiculous if you ask me.

Even if mpex became the default stock exchange with a shitload of stocks how can it reach a value of 1/10th all bitcoins?

Besides the fact that mpex was designed to take money from noobs, how can anyone explain the current value?
