bitcoin is so good that now it allows you to create additional applications to your blockchain to use fast small payments for goods and services.bitcoin will be used for payment.
No matter how good Bitcoin is when it comes to payment system, I still do not believe that it will become a new state since Bitcoin is being adopted by the government thus, preventing it to create a separate state or faction of people who believe in it. So that's it I think, the government adoption and regulation is the key why there will be no new state created for Bitcoin.
