The same happens in Reddit, for those who have been using Reddit most of them somehow related to Bitcoin. So definitely most votes will go on behalf of Bitcoin.
Bitcointalk = people interested in bitcoin and crypto in general.
r/bangladesh = people interested in Bangladesh.
There's a vast difference in between this two. Well, the population size is too low and selective because people with illiteracy and people who are not active in social media along with the people who are not okay with the internet, have not been counted. Majority of the people here in our local haven’t heard about reddit even.
The news doesn't mean anything. Bangladesh accounts for a small proportion of the encryption industry.
Your point is vague here. El Salvador is also a small proportion regarding the crypto sector but it has announced Bitcoin as legal tender. Don't you think that's an important announcement?
Also, I'm not sure which meaning you are looking for. That's not an important issue for you doesn’t mean not important for others too.
