Sure, crypto can't help everyone, but it might be able to help some. A lot of the homeless I'm seeing are younger than me so there is much more likely a chance that they can use and have an easier learning curve to something which might help them. For the older ones that grew up in times without using a computer then something based on what they are interested in and place them in an environment where they can learn and develop that interest and skills and get some remittance from it they could trade for everything they are currently without.
