but for my time here never came across any exchange issues that relates to double.
Do you think gambling sites should be allowing double account?
Apart from that, currently there are many local online casinos circulating in my country, sometimes I myself have an account on a particular platform and when I get bored I register again at that casino, it won't work if I use the same username, contact number, and email, only for me it works when I register with a different username, contact number, and email address even though I register with the same account name (bank) but a different bank so only the account name is the same, but it seems that this is included in having a double account, it's just that there haven't been any problems.
