Make sure to use a different password.
Anyone with just your username and password can gain access to your bitcointalk account.Judging by the details of the promotion there could be a chance that OP wants to know your bitcointalk accounts password.
I am not accusing them of stealing accounts but don't be surprised if you lose your account after signing up at this casino with same password.
You have been warned.
We cannot see our client's password. It is encrypted. So there is no way we can know the password of a user. We can only reset the password. But still, thanks for your warning/alert to the users. It is always better/safe to use different passwords.
