If OP do this correctly with the same address, I think the money should still there and if the minimum deposit is the issue here, maybe OP can add amount to his deposit and that site can easily adjust the balance on his wallet once ok, OP just need to communicate properly with that site and maybe, they can still solve this problem. This is another reminder to read ToS always and don’t deposit easily, you should always do some research first.
A rule is a rule if you deposit that is less than the amount required it will not be credited and the money is eventually lost in favor of the casino, that is what is we see or being reminded to us by the casino whenever we made a withdrawal I don't see doing this will solve the issue, well he can try but I doubt, with Bitstarz reputation, they will just blame OP for not minding what he's doing.
Once you have done it then it do automatically means that you are really that agreeing with their terms and they do have the full rights on banning/excluding/blocking on users account.
You dont have the right to whine if you are the ones who do violate their TOS but if theres something which you could explain off or valid argument then you could really able to do so.
