I don't think Bitcoin alone will make a country ahead in the world economy, of course there are factors that must be considered, El Salvador is a good example, they think more about Bitcoin more than any other country, comitted to Bitcoin and making it as their legal tender, yet they are still behind economy-wise, legalizing Bitcoin and thinking more doesn't actually make a country ahead, but I agree that Bitcoin can help one's economy improve, regardless if it's a first-class or third-class country.
