I have read many posts about Bitcoin helping the poor people in countries around the World but I would like to find out more about this.
No, it doesn't, that's a false information.
If someone has to buy bitcoin then they needed the money and if they have the money then they are not poor, isn't?
You are convinced by someone who thought bitcoin is a quick rich scheme, but it's different. Definitely, it made people to become millionaires and billionaires but those who are bought or just mined in 2011 and just held with them forever.
