Why are people are stuck with the idea that there can only be one dominating currency? BitCoin has shown the world that there CAN be successful, competing currencies so why couldn't there be more?

There can be just as many Crypto-Currencies as there are Nations, some valuable others not so much, but furthermore I think there can be Industry Specific Coins as well for Agriculture, Automotive, Aviation and most anything else you can think of.

All (or most) NOT controlled by the International Banking Cabal. Isn't that the whole point of this exercise?
