I haven`t such situation but possible it depends on time that you use this casino and your bets. Possible that your limits will grow some time later, when you`ll reach some limit of bets or time you are gambling.
I think that you ought to ask support about such situation and if it is possible to increase limits manually.
During last months I may have bet 80 mBtc, and it was a good month in terms of gains I would say. But everyone knows that in gambling you have good and bad times.
The support told me:
'''
There are two types of limits. Global and account limits. Global depends on the competition integrity and coverage and personal depends on the account activity.
They will keep checking acounts and improve limits if that would be possible in the future.

Feels like that's it for your account then and even them can't change it. Is this even possible on KYC'ed accounts or will likely be different? I haven't have the same issue since I'm not that of a regular gambler but it should have difference right to non-KYC and KYC accounts.
