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.
Actually cryptocurrency was not yet widely useful and even considered illegal in some countries. Cryptocurrency was its initial phase today and its adoption was still on the process. On the other hand, we don't know what will be the next discovery related to currencies. What is for sure is that it will all about digital advancement.
