Bitcoin already is, since a long time ago, a currency that can be used worldwide to pay for goods and services.
This has been true since May 2010 when laszlo paid 10k BTC for 2 large pizzas:
https://bitcointalk.org/index.php?topic=137.msg1195#msg1195You can't pay for goods and services with your local fiat currency directly to another person in another country, it's basically worthless paper until you exchange it for their local fiat currency.
But Bitcoin is accepted worldwide, without the need to exchange it into some local currency. It's a global currency since its creation because it lives on the Internet, which is global by nature.
Bitcoin doesn't need the approval of central banks or governments because it doesn't rely on them at all. That's by design, and that's a great thing.
That's certainly true, mate. By design, Bitcoin is already a global cryptocurrency. That's thanks to its use of the Internet to reach the masses worldwide. But even though Bitcoin can be used by anyone, anywhere in the world, it's still not officially recognized as legal tender by mainstream countries. So technically, Bitcoin is not a world currency even though it can be used anywhere in the world through the Internet.
Don't count on governments abandoning Fiat in favor of Bitcoin anytime soon, especially when they don't want people to experience true financial freedom. Surrendering Fiat, would mean surrendering control over the mainstream economy. And that will never happen. I'm fine with Bitcoin just the way it is, as long as it remains a viable contender against Fiat. Decentralization and censorship-resistance must be preserved for Bitcoin to stand the test of time. Who knows if it will be with us for generations? Just my opinion
