Can BTC become the world central currency?

At a time when the world is clamouring for peace and unity among the countries of the world- developed and developing.
There is a major limitation, which is the different currencies of the countries. These fiat currencies are controlled by different policies and economic situations of their different countries.
This posses a threat to global financial unity. As many countries are under banked. At the height of these challenges, came a pseudo human called Satoshi, who created what seems like 21st century wonders(bitcoin)

From 2009 till date, bitcoin suffered too many set back, ranging from disbelief to doubt about its future.
But 10 years down the tunnel is a great improvement and acceptance of the first cryptocurrency – bitcoin.
The huge acceptance lead to the creation of several altcoins.

Now many countries are willing to involve in the cryptocurrency world despite some restrictions in some countries because according to an African adage “No one knows the Goose that will lay the golden egg”.
I am seeing in the future where BTC will become a unified currency for the whole world.
