Will you come to that point that you are going to ask for KYC?
I might depends on location where MintDice placed their company, and license they have (if they have it). Most of online casinos don't ask for KYCs, but there are some exceptions, especially if someone withdraw huge money, KYCs are required, just in those cases.
I'm aware that there will be some instances that they can ask for it if they found trouble to your account. And if their local government requires them to do so but it can also be part of their plan in the future so that's why I'm asking.
Indeed you can play on MintDice.com without creating an account. We have installed automatic account generation that allows you to play without verifying your email address. More information about this
here.
I like this feature, most casino's should implement this.
