I guess bitsler has some policy that one is not allowed to profit from the faucet ?
If so, bitsler should state clearly the rules of using the faucet.
14.4. Getting an edge against the casino without any risks is FORBIDDEN. (e.g playing with faucet, winning from faucet then depositing to withdraw all the balance etc.) Only for earnings from faucets, we reserve the right not to authorize withdrawals.
