because if in a physical casino when entering a gambling place you will always be asked for the identity of gambling security but for online casinos minors can use fake data to still be able to gamble.
Actually people that are 18 ain't mentally much different than 15 y.o. people. I know how dumb I was when I was 18 and I can tell there wasn't a great difference with my 15 years old self. So just because a person is over 18 doesn't mean he will make wise choices instantly.
Most people stay dumb till their 30's and some people stay dumb forever till they die.
On the other hand I've seen 15 y.o. kids that are way smarter than most adults. These kids were able to think and act like an adult. It is like they were living their 2nd or 3rd life... But let's be honest most people ain't like that.
Yes, that's quite funny mate and I definitely agree to the words you are saying because that is true. I also don't feel the difference when I was still 15 years old and even when I'm already 20 years old, I may have a bit of improvement but my priorities and mindset are somehow the same. Everything are almost the same because even a 20 years old can still be called a teenager, not by term but by choices that they made.
Hence why casinos and online casinos are requiring the gamblers to be at least 21 years old and above because by that time, most people do know how to weigh some things.
