Talking about impact on our society, I have found that there is a very interesting new project, it is an unconditional basic income project called Swift Demand, every single day you receive 100 coins, without any questions or conditions. With altruistic motivations I would like to invite people to join this platform, maybe the coins here have some real value someday and we all get basic income through blockchain: https://www.swiftdemand.com/users/sign_up?referred_by_name=x777
