How are they going to get there bitcoin, they have internet or they have gadgets? Then they can work for that if they has internet, many ways to earn bitcoin online why dont they try some. Because if your capable of doing things to survive why you still need to beg for cash or bitcoin?..
@xhoondilan, i think we should forget about HOW;
what is important is if, the homeless person can be able to cash it or withdraw cash from BATM without having to go through the hussle with bank's or credit card companies considering his/her situation. i can as well pull out my smartphone to drop few coins from my wallet to the beggar.
Atleast, as long as this is another hacker who is requesting for ransom.
Thanks
