Edit1: Thanks for everyone replying, I have decided to not online gamble as now I know it is illegal, so to people who was wondering my age, 15.
I am glad to read that our many replies actually helped to change your mind. 15 is not so bad, in a few years you can gamble and can actually see a casino from the inside. I still remember going the first time to casino in a suit, losing a bunch of money but still an awesome experience for a night out. Great food and wine. But overall you are not missing out on much. Also it's better to just save your crypto coins for now until your are 18.
