hi i was using rollbit and got from a buddy tip of 500$.
now i was trying to withdraw this and my account got banned right away and the money was gone.. account was back to 0.
The account cannot be banned just like that, maybe they have suspected you of some suspicious activities while trying to make withdrawal, so instead, they will render the account under suspension until they have every satisfying information required from you.
the support open my account and asked me to kyc my self. i did it and they said i got banned from their site in the past by i didnt it was prob someone in my family that got banned but not me and i proved that with my personal id and everything!.
we cant know who is lying here and since you're not putting any evidence forward, we may not know the exact approach in dealing with this, but i can bet you, this should have nothing to do with your family account banned, maybe you have something that linked you with the banned account or did the same thing that led to the first ban on your family member.
