Do you think it will be true? Are you positive towards bitcoin's future status?
I don't believe so. Governments will just not let us do this. I think that aiming to replace any currency is bad way to take. We need to soften the banks and governments and persuade them that we can coexist, what will happen after that is up to consumers.
But we are still small and fragile,that's why we can't fight the battles that we can't win. We must pick our battles very smart. Or I am afraid we can get smashed.
I think that BTC and fiat will complement each other in the future.
