This has been discussed before: blockchain would be the tech that would change how the world handles things. If we think that computerized ledgers and databases are already advanced and secure, what more if we would be able to integrate a transparent yet pretty darn secure tech on the way we handle our records? This would be a cost-effective record keeping technology if implemented perfectly, and it's just one application of the tech. It could be implemented literally in almost every banking and finance services alongside automation processes in the private and public sector.
This means the world has unconsciously received the presence of Bitcoin. Due to evidence of security and speed of blockchain technology brought by Bitcoin. I believe that bitcoin has a bright future, and countries in the world will simultaneously recognize and legalize bitcoin.
They see bitcoin as the first true application of the blockchain technology and it proved to be successful. However, I think that there still wouldn't be a paradigm shift towards bitcoin as everyone is still busy cuddling their fiat and banks. People would gladly accept the tech but bitcoin? It still has a long way to go IMO.
