Money changed its shape through 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 it's going to be a cryptocurrency or something else.
It is possible to have a new coin in the future after bitcoin because as what we have right now our money features are exchanging their physical appearance and I think that is also how cryptocurrency will improve even more in the future. New coin or maybe new features of cryptocurrencies in the future. We are still not yet in that phase so maybe let's just stop assuming something new. LOL. But the better version is good I know.
