I agree with your goals for positive things, but if it will be held who will hold the donation and be a trusted person, honestly I want to share some of my results from the lottery for the poor, hopefully it will be of help to the person poor.
I do not think you need to find any person for this. As far as i know there are so many NGO and charity organizations in everyone country and we can donate some amount of gambling profits there. Of course there will no special organization who will accept gambling money as charity.
NGOs and charitable organizations in my country do exist but to receive donations from gambling does not exist, and I have already given to the organization but rejected for other reasons, well I hope in this forum there are those who accept donations from gambling so can be channeled to people in need.
