Even with the use of email address alone you can explore the casino easily because you will immediately receive the login link through email if you register using email address. There’s no need to input password because you will receive email link whenever you will login to the casino which is very easy and safe at the same time because you can’t be a victim of phishing.
I think this is the most convenient way of making an account in a casino. I have tried in other gambling sites too particularly duelbits and I believe this has been the trend now. No more recording your password that you might just forget overtime, but with email that you are using in a regular basis, it's easy to just click and log in.
Waiting for the big event, hopefully there's someone from here who could win that huge reward.
