I am similar to OP, I gamble for fun but of course everyone wants to win that's part of the fun. If I do win big one day though I would do the exact same thing I do with my big bitcoin/altcoin earnings, invest it for my future. If I won so big I had more than I need for my modest lifestyle I wouldn't share my wealth but rather I would start a business that I feel is beneficial to the world, for example it could be something related to solar panels so I can be a part of a business that reduces climate change.
