The topic is quite popular but it's not that much trending over the world.

I've checked the global volume of several popular topics with ahrefs. Global search volume shows the total number of times the keyword was searched last month across the globe.

As you can see, Bitcoin is popular, but ...

League of Legends - 12M


Trump - 9M

I just want to say that people are not keen on bitcoin anywhere in the world. They have tons of other topics to talk about and bitcoin is just one them.
