I'm coming back to this question because I've new experience with earning Bitcoin. You could ask for Bitcoin at Christmas. No matter how funny it sounds at first, but alot of people get money as Xmas present and the money adds up and become a large funding. You could ask for this funding in Bitcoin or ask for money and exchange it to Bitcoin.
I don't know if you are encouraging begging in the forum but I think it is forbidden in the forum rules, I don't know if the punishment is a temporal ban or you are banned for good but don't do it.
