I was close to Living On Lower Wacker Drive in Chicago at one point in my life. It scared the Hell out of me. I got my rear in gear, and it didn't happen. Lucky me. However as I read your article here, I wondered how Bitcoin could be a help to homeless and disadvantaged people. I was thinking of some kind of Blockchain, or token that could easily be given to a person in need. I did come across this article, which might be helpful. https://www.wired.com/2013/09/bitcoin-homeless/
