If you really want to save BitCoin and keep the bankers/forex traders from having such an effect on BTC's value? Quit comparing it to USD. Take only BTC/LTC/devcoin/etc. and ignore these other fiat currencies. As long as cryptocurreny values are compared to fiat currencies and we do not set (and stick with) what we feel the value to be, then we'll continue giving the Big Banks and forex traders all the power they need to destabilize our nascent economy.
Will never happen. Fiat is Bitcoin's only link to reality, to real economy. Just like the rest of fiat currencies, Bitcoin is created by fiat. Unlike other currencies, Bitcoin's worth is not backed by political clout, military might, or an economy -- it's backed by nothing.
And who cares? If you hold 1BTC to be worth something you've created, whether it be digital or physical, goods or services then that is the worth of a BitCoin. Do you think people all of a sudden said, "Well, this gold is worth 1,000 chickens, so unless I get that I won't sell." No, worth and valuation came as people began trading with gold. Some people got more for the same amount of gold, others less. Prices weren't really fixed though merchants who could go long distances knew how to play the markets enough to make a real killing (but even that didn't come around until later). The value of some amount of gold was 1,000 chickens for some people, and for others it was 20 horses (which might be worth 1500 chickens to someone else).
The point is BitCoins (and other cryptocurrencies) will only have value so long as it is used by those willing to accept a certain amount of Satoshis for whatever goods or services they offer. The same was true of fiat currencies before they were fiat. Their worth was determined on how people bartered with them. When governments stepped in to regulate their worth, it pretty much spelled their doom due to future inflation.
