Crypto casinos are becoming popular and also growing faster than the traditional casinos because the crypto casinos provides privacy more than the traditional casinos. But why people get addicted to gamble is because they are gambling because they want to make money from it. Gambling to become rich will just ruin one's life because the purpose for gamble is only for entertainments when a gambler begin to gamble to make money and become rich they will become addicted to gamble.
Yeap, I would agree with you that privacy is a big factor in the reasons why crypto casinos are becoming more popular than traditional casinos. I would also say that the money transaction or transaction fees are lower than traditional bank-based or physical casinos, and that is why people are currently becoming more interested in these types of casinos.
And also, think about one thing, you cannot gamble in all types of casinos through your local bank deposit, but you can easily gamble in world class casinos through crypto coins, these are actually the reasons behind the increase in popularity of crypto casinos.
