Well, that is slowly going to happen, wether people like it or not. The technology and adoption is going quicker than any technology before it. It's going so fast it's hard to keep up with all the new innovations. From tipping services like SmartCash that is going to possibly explode (you can tip on steemit, discord and reddit using SmartCash..) to IOTA, EOS and other huge projects.
Even if government "backed" money will still exist, it will only exist as ONE currency in the future. It will only be to exchange other currencies. You make your money from playing computer games getting tips..or blogging earning steem..or other things getting paid in ETH or whatever. You exchange that to fiat..PERHAPS. For a while..but ideally not on the long run. Ideally, for us..crypto currencies are valued against Bitcoin or ETH or EOS or LTC..and it will be possibly to purchase anything with cryptos.
That is why #Hodl is a little bit misleading, because yes, we should hodl crypto currencies over fiat..but we must also dare to use them. We must transact. Thats the only way we can grow.
Technology is moving really fast most are failing to catch up especially on the crypto movement. They will fully engage with time. Are on steemit.Chat too? @wesakab is still my username there. Maybe we can discuss more from their. Anyway great post though! Great work too. Thanks for sharing.
