The reason I'm saying this is because it's really coincidental they would KYC me after I win big, after gambling on it almost weekly for 2.5 years.
have you submitted KYC before or this is your first time submitting it?
just curious, after winning $50k, did you request a withdrawal? if you did, as far as I know, casinos usually would request KYC from people who are going to withdraw a huge amount that hasn't gone through KYC verification.
The money is probably lost because I'm currently straight up getting ignored by Rollbit and getting a response that they are "awaiting their third party", atleast I can warn you guys about their shady practises.
don't lose hope, I've seen KYC-related cases get resolved after a week or two sometimes even a month. good luck and congrats on winning $50k, I hope your case gets resolved soon.
