So far I think its only people or organizations that are trying to create a new crypto currency to just be out there and maybe one day compete with bitcoin. But what if a government decides to create a country's own and legit altcoin? How would that affect the whole scenario? Will it be an instant success, especially if the country is big enough in population or has decent enough international trading going on.
I guess you were sleep this all time dude, governments are already doing this just by transferring bits of code as valued credits and then you could get your hands on paper cash at the end just like any crypto currency.
Also using open source ledger stops the governments influence that's why they use as closed source.
