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?
Nothing is wrong with FIAT, but the central banks see the rise in crypto currencies and want to profit off it. They are aware that they can't control all these coins online so they bring out there own coin. In my opinion the central bank crypto currencies are just another form of FIAT, they are another currency being controlled by the government. Time will tell but it doesn't seem likely that the usual crypto investors is going to switch from bitcoins into the central bank coins.
