Re: OK but...
The early ones did have the decentralized and uncontrollable aspects as goals, but newer ones, including anything a government comes up with, have dropped it. It's likely that governments wishing to maintain control over their monetary system will attempt to regulate or prohibit those cryptocurrencies that don't continue to have them at the helm. I don't know how successful that will end up being, but I'm in the position of disliking every side of it. I don't much like the cryptocurrencies, but I also oppose governments thinking that they should have a monopoly on exchanging value.
