With the likes of government , NSA ,banks etc..Could they coordinate into creating their own crypto to defeat Bitcoin?
Creating something like 'Legal Bitcoin' , invest and pump, make it succesfull? Make markets aware
Maybe even create their own cryptography where they could still be able to decypher code if they needed to?
Yes it's possible for government to create their very own cryptocurrency but I don't see it will have a purpose to defeat bitcoin.
In the first place, why they should defeat bitcoin? It doesn't make any sense honestly. They can just ban bitcoin in their respective country if they really want to get rid of bitcoin usages there then stick with the idea of continous upgrading of money payment system which is happening right now and results is very good especially with the current status of bitcoin network.
