Not likely, at least within the technologies of modern days. There are two points of concern that makes crypto an unwanted guest for governments - anonymity and impossibility of implementation of any monetary control tools. Anonymity goes against the intention of all governments to track the money flows and thus avoid frauds, money laundering and tax evasion. Monetary control, on the other hand, is an essential tool that allows the country to solve the financial crisis for a price of further, less critical issues. Cryptocurrency may be applied as a payment method that has similar legitimacy status with fiat currencies, but that will be something new, developed exclusively for governmental usage.
