Last year I gambled always using my local currency, but I increasingly realized that my activities could be monitored easily if I made transactions with my bank continuously, it was very scary if I was caught by the police because my country prohibits gambling activities, and now there is a new system that has appeared in my country such as recording all transactions made, fortunately I never use local currency again so I can breathe a sigh of relief, now I only make full transactions in gambling using cryptocurrency, privacy is very well maintained.
Everyone wants to protect their privacy in everything they do, including gambling. Crypto allows us to do that, although some casinos may now require KYC, which can be uncomfortable for some.
It's perfectly natural to feel uneasy if our every activity is constantly monitored by the government or relevant agencies, especially if gambling is prohibited. So, we choose options that protect our privacy as much as possible, especially regarding transactions.
Of course, everyone wants to play in privacy while gambling, especially in countries where gambling is not legal and there is a strict ban from the government. For example, in my country, gambling is not legal, gambling is completely illegal, so everyone from this country likes to play in privacy and legalize gambling. Of course, the transactions are more transparent for gambling because the first thing to do for gambling is to provide money.
