No offence dude but bitcoin is a useless currency for the homeless. How are they going to pay for anything without computer or phone...
Exactly unless you are giving them a phone to use haha.
There are many programs where they can get mobile phones. But I think it is limited to dumb phones with text and calling. So I would agree them having smartphone to do this... slim chance.
You might be able to do a charity for homeless (but it would be hard as providing proof and getting people to donate will not be easiest journey). But I think at end of day the homeless would be better off with fiat.
It is sad but I don't see them carrying around a bitcoin wallet over cash.
