Not having 2FA protection for members is a serious no go for me, i woudlnt deposit any money there without my account being protected my 2FA.
I didn't register yet, but i agree with you google 2FA is very important in crypto online casino without that we'll easy lose fund there.
I dont think will try all new casinos if we must made an account to try, because all we know many new site come now and ask us to register in their site first just to try. Spamming email is annoying i dont want my email just full with spam message, so like others said better made demo version first before register or made an account.
