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.
For me, it is still a long way for cryptocurrency the fiat money that is implemented is still reliable in a lot of ways maybe after 10 years cryptocurrency could be implemented too.
Fiat money is still the best way and most convenient way to use in buying things and also in a physical store most of them do not even accept cryptocurrency as a payment and even bitcoin their are only a few stores that accept this kind of payment method because it is not yet implemented and also not yet regulated I'm not sure if we could use the bitcoin as the main currency because the market value of it was so volatile and when you use it as a money it is difficult to check the market value, it is a hindrance if you lose money in a small time without even doing anything.
