If I have a chance to win a very big amount, why not? Sharing gives good karma in return. If that happens I will prioritise those who are really in need. Even during the previous bullrun I used to share some of my income to my family and relatives a simple act of generosity but I wish I can also extend and help other people too in the future.
you can donate every amount using cryptocurrency too, using this website

so every time you won and you can spare a few bucks to donating
