the goverments have plan to create their own cryptocurrenicies, so the btc and eth was just testing currencies to see how it works and get people to use with cryptocurrenies?
first whats wrong with fiat currency? the cash is works good nothing wrong with this.
second how they are going to control how much to issue the currency and how the value will be backed?
and by who the transparanscy is guranteed?
This is the question that we will never know. We don't know who created bitcoin but we know why he/she/them created it but at the same time we don't exactly know if that's the real reason or the reason that author wants us to believe. It's possible that governments are behind it but at the same time I doubt that because it was proven years ago how hard it was for governments to track bitcoin transactions (maybe it was done to blind us on a long term?).
There is nothing wrong with fiat currencies, I don't want full digitalization because in that case governments will have full control on numbers (money) and will be able to manipulate them the way they wish, they even manipulate current fiats.
Btw who says that governments plan to create their own cryptocurrencies? Any currency made by them will be far from cryptographic.
