Bitcoin can't help an entire country. but it can surely help the person who use bitcoin if he's poor. and if a country have a lot of bitcoin users then it will surely be beneficial and for that country.
bitcoin need some contribution. if you contribute with bitcoin and crypto currencies . they will reward you for sure. but if you think bitcoin should give you fortune without doing anything just because you are a poor person then keep dreaming.
You are correct, dude. Btc can help and improve poor people, in Africa, Asian countries. They can make bitcoin by solving captcha, posting and do social campaign. Although the money is not a lot, it still can help to improve their life.
solving captcha and social campaign i think not only in asia or afrika. All people in all country for the first time will doing that. Especially for people who do not want to spend their money.
