I read about cases when 2FA does not help
There are many cases of robbery or hacking where 2FA is bypassed. So while that is indeed an additional security layer, it is never a guarantee that your account is 100% safe.
And don't forget that hacks don't only target individual accounts, identities, deposits, etc. What's even more damaging is when hackers target the platform or the site itself or its wallets. This happened to the giant platform Stake just hours ago. This could happen to nitrobetting as well. This could happen to any centralized platform.
Yeah, just recently read about the news and I am sad for Stake.com.
You are right, it's not just about the security of the users so 2FA's might not really be relevant at the start. First, a gambling site must prove its own security because there are too many attackers that will start from them before they can take the information of their users. Even with 2FA's, and e-mail verification, a gambler can be hacked when the hacker goes through the website first by stealing the information from them.
But I guess nitrobetting is a starting business so they are still upgrading, I hope the upgrades will not stop after this.
