Hey mate, I’m not trying to defend the casino since I don’t have any info about them but according to your conversation with the support/owner, Your casino account is inactive for almost 5 years which means your account already expires. All casino nowadays have this kind of rule in their ToS that ranging from 6 months to 1 year inactivity before your account got restricted.
I think you have the right to claim those referrals that you earn when you are still active but the support has a valid point regarding your existing referrals since your account is already closed. You should read always the ToS so that you will be aware on the casino rules. I agree on the support because I knew exactly that kind of rules exist on any casino.
That's odd because if his account expired he wouldn't be able to log in. But with just $10, I think that is also a warning sign. Not saying this is already a scam casino but a warning sign to all not-popular casinos I guess is what users should be cautious of.
But I wonder why OP chose this casino over hundred casinos in crypto that are well-known to the community. Iff he is up to making more than $10, he gotta be signing up to the casinos that have been in the crypto casino business for a very long time.
