The same for me. There's nothing wrong in giving out some of the winnings but we must always think of our family first before we think about strangers. Will there be enough money for the family if I give a portion of this winnings? Will they even accept the fact that I have given some of it?
It's not wrong as long as it is sincere and you are not stepping on someone else. There are people who don't like being given such things or money because they feel like their ego is being stepped on and so we must be careful about the people we choose to give the "balato".
As a Filipino kid, this was already a thing for me, we play cards and when I win I will give back a part of my winnings to the kids who are cheering for me. It's a traditional thing that already happens even when you are young.
