You were too small when you started your first gambling. Gambling is meant for 18+ ages but it made you more experienced as you started early. Even I remember my school days, when we used to fight over pocket money and then invest those into something which made me happy.
I think OP stated about crypto gambling, not in fiat gambling. Even 10 years of age know how to gamble at this generation.
Well, I've learned to gamble when I was a newbie here and that was around the year 2016 and until this current year, I still gamble using my crypto earning. Nothing's motivated me aside from having a profit when I gamble and I hope on that every time I gamble. That was a poker casino and dice gambling but I stay longer on dice gambling and so on with different feature gambling sites. So far I didn't know how much my profit but I remember before when I was hit the jackpot prize on Prime Dice. Gambling makes me entertained will rather than playing video games.
18 is only the legal age for gambling but that does not mean that a 17yaer old guy is too young to gamble, I feel 17 isnt too young but not allowed. I started gambling when I was 15 and I knew a lot about gambling even better than some adults then. I read about the dangers of gambling, the mistakes and the habits that can easily lead to gambling addiction, this helped me to be a better player because I applied all that I have learnt into the game. The only challenge then was with my age, so I only gambled on sites with anonymity.
No one told me or introduced me to gambling, I was only doing a research and I ran into a gambling topic online. Then I saw list of gambling sites and I decided to try on one of the sites. I made about $20 AND I PLAYED WITH LESS THAN $50.
