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?
They won't defeat bitcoin,they will just force policies which will make people stop using bitcoins and use their coin instead.They government will always control the chain and will have the control over the transactions.So don't expect another "bitcoin" from the government.To simplify it further,government would levy small service charges on each transaction.Also their mining will be private : )
