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.
inb4 but minerz: Real currency isn't backed by the nice men who make the plates and run the presses that print the bills -- that's just how money is printed. Bitcoin is similarly not backed by the nice miners who run their rigs 24/7 -- that's just how bitcoins are made.
