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?
I am also of the opinion that BTC and ETH were needed as startups to roll out all the processes. In reality, no state is interested in the emergence of surrogate money. Of course, the states are considering the possibility of creating their own national cryptocurrencies, and this looks more real than the acceptance in the world of BTC or ETH or other cryptocurrencies issued by someone who is not clear and for what. Are you asking what's wrong with fiat money? Well, look at the dollar, it is printed without restrictions, but is that right? I also do other countries that now have problems both in industry and in financial and political spheres. What will the national cryptocurrencies give? First of all, this is an opportunity to get rid of old money, which is now of dubious value, here there is a storm of internal and external debts, the cryptocurrency will have a limited amount and be distributed quickly, reliably and it will not be possible to steal or commit muddy schemes. In general, I see it as a new system that is more perfect and efficient than it is now.
