do you believe with bitcoin in the future can replace fiat as a number one currency?
It might be happen if bitcoin has strongly influence worldwide to replace our local currency.
Bitcoin also need stable price and more advance security system in order to maintain bitcoin performance so it will gain new bitcoin noob's attention
I strongly believe that would happen very soon. People already have lost their faith with fiat currencies just due to the situations happened in Greece. Everybody wanted to save their wealth most securely for next generation. Bitcoin will help them to help itself to reach the number one position.
