Why don't you want to wait for a while? No such service can send and receive instantly even in our real life without any of waiting time. We need to wait for a while, and maybe it's less than 5 minutes while you can do another thing to wait for the balance. I think in all website, there is a waiting time to see the transaction getting confirmed from the network so whether you like or not, you still need to be patient to wait.
It doesn't matter if you are waiting for less than 5 minutes because you could still play after your deposit arrives in your account.
