Why is a email verification needed? In order to send emails from our side about logging in or withdraw/deposit emails we need you to verify. If we do not do this we can be seen as spam and we can be added to so called blacklists which will result in emails from us will be never received by anyone. This means also that we can't manually verify any account.
