Using Bitcoin or other even more private cryptocurrencies like Dash will mean no gambling transactions appear on your credit card or bank statements. That’s a positive thing for privacy since gambling is stigmatized by most other people who don’t enjoy it, slotwallet including most bankers. Since you’ll likely be convincing these people to give you a loan at some point, it’s good to keep gambling transactions off your books. You will likely have to share your details with the casino, though, due to Know Your Customer (KYC) laws. If you want to go fully anonymous, there are crypto casinos with no registration. They’re as close to an online private gambling club as you can get. But that’s probably going a little too far for most people’s privacy needs.
