Money changed its shape through the history. As from non-monetary exchange to the need of having money. Fast forward to our current banknotes which are in my opinion slowly dying with bitcoin taking over. Many discussions are being held if bitcoin can be the primary currency in the world. Let's assume it can be. Everything has an end so what do you think will come after bitcoin? What will money look like hundreds of years from now? I predict its gonna be digital of course but I'm interested if its going to be a cryptocurrency or something else.
100 years from now? that's an insane imagination we need to give opinion about that, but let's get wild here. When that happens (cryptocurrency ended) my bet would be, our technology will be super advance compare to what we have now, we're going to feel like we're living back in the stone age looking for that 100 years from now. We might even use built in chip that contains the dedicated money we will spent in our entire life, like those sci-fi movies we watch.
and that's pretty scary for me, because what if you are a person who spend his money on random things that you only wanted, you'll starve to death by that.
