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?
No! Governments are only afraid of bitcoin and decentalized cryptocurrencies because people are continuing to adopt it, they already know cryptocurrencies are the future currencies. But, governments are only compromising what cryptocurrencies are, cryptocurrencies are supposed to be decentralized, but governments are working hard to make it centralized it.
first whats wrong with fiat currency? the cash is works good nothing wrong with this
When the governments have already dawning to know fiats are not accurate enough when it comes to transparency, and that cryptocurrencies can be created in a more transparent way and hard to edit or manipulating ledger unlike fiats.
second how they are going to control how much to issue the currency and how the value will be backed?
Governments are governments, their centralized cryptocurrencies will be controlled like normal fiats which are depreciative assets. So, governments owned cryptocurrencies which will be centralized will be manipulated in price and value like fiats, which means the governments cryptocurrencies will be depreciative assets, unlike decentralized ones like bitcoin that are appreciative assets.
and by who the transparanscy is guranteed?
Government owned cryptocurrencies will be transparent if they use a transparent and impossible to edit ledger, but let us see if such will be the case. But, know that the centralized currencies, be it fiats or cryptocurrencies will be a depreciative asset because it will be subjected to manipulations in term of prices and values.
as this pandemic laws are getting more strong and we will soon have more rules but not rights so i dont think we can ask anything at all lol
