So, I was sitting side to side wit a good friend of mine this evening while having a chat about making money, we talked about several ways we can make a lot of money in the most possible short time, in the midst of the options we both came of up, I brought up the option of gambling, suggesting it to him as one of the most easiest and fastest way to also make money if and when one is lucky, he agreed it's a good option but complained about the possibilities of betting addicted, and as a result, losing back all the money after winning it, then I told him that if I won like $100,000 from gambling, I did quit gambling forever, he laughed and screamed impossible, he said that the more money one makes from gambling, the more they get hooked, we argued about this until we both decided it was time to go home and rest.
Your friend is correct. It is unlikely to stop gambling when you win a big prize. Even if you understands that stopping is the best option, you may return again someday. It must be a temporary stop only. When you have spent all the prize, I'm sure you will return to gambling again. If you really want to stop, you need a stronger reason. 
Anyway, why you choose an option of gambling? Don't you think to trade crypto coins? This is also a fast way to earn money. It is more secure than gambling if you choose spot trading. However, it requires a lot of money if you want to get huge profits. But the safe thing is that you won't be addicted to gambling if you choose trading.
