The only way to connect the whole world is by bitcoin.

If the OP means that Bitcoin could connect the world through cross-border payments, then its already happening. The usage of bitcoin is increasing everyday, just imagine how someone in the other parts of the world sends funds to his love ones across the globe and the transaction is done within minutes or hours and without any third party involved. But if you are implying that bitcoin could be a universal currency to connect the world, then I doubt it will happen. Nations still have their traditional fiat money, and banks, one of the oldest financial institution wouldn't just allow their business to be overrun by cryptos like bitcoin.

I think it's been a long time before the crypto is closed worldwide because many countries are not accepting cryptocurrency due to some factors like the banks of countries and the goverment of the countries.

I think To the countries of the whole world Accept the bitcoin What will happen with bitcoin will make the currency world interconnected What can you think

I think everyone is connected to bitcoin, everything is connected via the network, what else do you think if everything is connected?
Maybe your question must be fixed again, or are you still a beginner to get to know the world of bitcoin?

The world are already connected with the power of the internet in which nations could now communicate fast and easy. Facebook messenger alone are for free that even their video call service are very useful in our everyday life therefore Bitcoin can make the world to connect as currency but without internet still it will be totally useless.
