I was withdrawing multiple times with no problem (all to the same address), how is it any different this time? Why they want me to provide kyc (picture and back side of ID/passport) to withdraw less than $100? that's a red flag. Any decent casino will disable your account and at the very least let you withdraw your deposit!
The KYC and AML policy isn’t so simple as it used to be a few years ago, the withdrawal amount doesn't matter anymore. There could be several reasons for asking you to complete the KYC verification. I can understand your dissatisfaction here as I have faced similar situation on two different casinos. One of them allowed me to withdraw without the KYC verification requirement, but I was forced to complete it on the other one. My withdrawal amount was small too. BTW, they have asked you to complete the level 2 KYC verification only, which isn't complicated. Shuffle team hasn't done anything wrong here as the way you are trying to highlight it.
