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.
Not sure if its really possible for a country to have thier own altcoin, country's central bank would mean useless.
But granting this can happen, bitcoin might just be one of the coin with high value. It will be good for us.
