i was able to register deposit and play at duelbits with use of vpn . they hit me with kyc with withdraw request
You are still lucky that Duelbits will just ask you only KYC to withdraw your funds because if you are using mediocre casino and committed this same violation to there ToS. There's a high chance that they will freeze your asset and ask you too complicated documents that will let you give up on claiming your funds.
Undergo the KYC or leave it there is your only choice since you are responsible to your action due to Duelbits didn't forgot to remind you about this on there ToS when you click agree during the registration process.
Yeah, in some casinos, they have potentially banned you already for breaking that one rule against them. But if duelbits has asked you for the KYC and they've detected that you did break the rule.
They still have spared you from that punishment and are looking forward to the compliance that you're about to do so that you can still get your funds as you request a withdrawal.
