Is KYC verification very important to crypto gambling websites or this has something to do with their regulations rule? Where can one gamble with zero verification requirements?
Some crypto casinos KYC are required, some other casinos KYC are not required, there are also crypto casinos that require KYC when withdrawals are outside of their rules,
for example: withdrawal max $10k without kyc but the user wants to withdraw money/crypto above $10k, most likely kyc is required to prevent things that are not wanted or harm one party or both parties.
For this reason, KYC verification is important or not depending on the rules of the online casino, but you can still choose the two options and make it easier for you to gamble, in this forum there are casinos that don't need kyc only you use Authenticator (2FA) only, without kyc, the choice is yours, definitely kyc or not, if not sure about kyc, choose an online casino that uses the (2FA) method, nothing compel.
