Nice ideas on using steem or bitcoin. I think you are right about theft and bullies - I had a few more thoughts on it.

Even public access to a coffee shop like place where kids could use computers for whatever they wanted and find shelter might be helpful. If you build up enough value you can make opportunities for yourself (this is difficult for everyone though). It is very tough to know what is helpful and possible to do without being there in their shoes. I have heard that bullies taking paychecks in order to provided “safety” is a problem in some countries.

Having funds on your own personal cell phone may not be as dangerous as going to work in a conventional job that pays well without having a home and some community support - I just don’t know. At least with a cell phone you can lock the contents with a pin and it is not as obvious as carrying around a wad of cash on the street. (Perhaps easier to hide?)

I wish we knew what would be of the best help.
