Hard to said this but we must be truth to ourself. Gambling is the most risky among all the investments ventures and it is really very difficult for you to continue making profits. I believe that currently we should not hesitate to make this prayers that God should put his favor on us and for us to keep making many winning trade than 2018.
In other words, you pray to the gods that he will pour luck in your investment in gambling. I think it's acceptable to just believe in luck than to believe there are strategy in gambling because it is where greed start and addiction will follow.
