that would be awesome although i dont think it will happen in my lifetime im 40. i can see a digital currency as a backup. Fiat (cash) is hard to get rid of totally. We are talking decades away before Fiat is eliminated permanently. You are talking about everyone, every business has to switch over and adopt the new digital currency. It would have to be voted on and agreed by the all ppl. Dont get me wrong I would love to see it happen in my lifetime but I highly doubt it. I say in 20 years we will start to see the beginning stages.
