If there is no stability in the value of a bitcoin how can you expect it to be adopted? If you sell me something today and I pay you with bitcoins on what basis are you calculating how much coins I should pay you? Do you just pick a number out of thin air? No, you peg it to a Fiat currency and if those bitcoins are worth a 1/4 of their value a day later wouldn't you be a bit pissed? How can bitcoin be widely adopted in that kind of environment?
I have to disagree to peg it to a fiat currency. Never has in history the world over involved massively in all fiat currency and now much countries are debasing their currency in a mutually exclusive suicidal attempt to increase their countries respective exports. There are serious consequences to debasing one countries currency. The Federal Reserve Note since 1913 has lost 96%+ of its value as its debt has increased 5,000 times. Hows the hope and change thing working out now? Peg it to a basket of hard assets and by God do not let the CFTC regulate it; like they do to the price of Gold/Oil. Starve the beast...
