All over the world?
I'm not sure if it's clearly stated all over the world.
Why?
I don't know 100% whether the whole world knows about Bitcoin or not. Because there are at least 193 or 273 total countries in the world. So, to be honest, I personally don't know for sure whether Bitcoin has spread throughout the world, in all countries in the world.

But, at least, just check the local boards on this forum, we can find so many countries listed with discussions on their respective local boards in this forum.
 

In my country, Bitcoin is not legal tender and it is even prohibited to use Bitcoin as a means of payment. However, here, Bitcoin is legal as a commodity asset. So it is very natural for trading or investment or anything related to crypto projects. So actually it's no surprise if one day I meet random people everywhere who are talking about Bitcoin or crypto trading and the like.

At first I was a little surprised to find someone opening a trading application (I'm sure it was a local exchange in my country, I glanced at it from the side), while at a bus terminal. But as time goes by, it seems to have become normal.

However, strangely, even though it is quite familiar here, most people still hide our activities in crypto, including me, in fact no one seems to know that I am also active in crypto, and I also don't know if other people are also active in crypto. Because indeed, even though we are familiar and often have conversations, so far, there has never been a conversation related to crypto.

Because perhaps, apart from state law, there is still a debate regarding crypto in religious law. That's why maybe it's a bit of a shame to avoid discussing it because there could be differences of opinion and that would actually not be good.
