To be honest, I don’t know a single crypto casino where they check for more than 24 hours. Roobet, rollbit, betfury were checked very quickly, I can’t say that these are small casinos. I'm not trying to somehow speed up this procedure, it's just a very big minus
Some of those casinos that you mentioned actually does a pretty thorough KYC check as well and on some reported cases was that it was longer than 24 hours for sure (might even take few business days)
Im not sure how much were you trying to withdraw but is it $90 ? Sounds pretty weird for a $90 withdraw to even request a KYC unless you did something weird on their site
duelbits is a cheap company that cannot withdraw $90.
Your best shot is to wait for now, complaining in this thread probably wont even help you on your case
