It would be good to allow players to play on the site without the need to register an email address with the site, I believe some players would prefer to have more privacy on that area, especially in the world of crypto-currencies gambling, adding in a faq page would really help out new players on the site too.
If you lose password there is no possible way to restore account. 
Email verification and 2fa is must-have for gambling site.
