I also come from a 3rd world country and what I feel is that bitcoin is growing in those countries more than in developed countries. Because as you know, life there is extremely difficult due to inflation, and government corruption...people are always looking for solutions to escape those bad things so they will easily approach and accept bitcoins.
But there are still people's misunderstandings about bitcoin. Because people's lives are poor and ignorant, many people may fall into fraudulent projects labeled bitcoin, thereby having misconceptions about bitcoin.
You can also see that the most active boards on the forum come from third world countries rather than developed countries.
Even inflation and corruption are big problem for third world countries, how can they own Bitcoin if they're poor in the first place? Bitcoin doesn't solve their issues because they didn't earn much money and they will loss when they send their coins.
The reason why many users from third world countries are more active than developed countries because signature campaign, if the forum completely ban signature, I believe only users from developed countries can maintain their consistency.
