I have to disagree on this one, it is not actually necessary to pray to God so you won't be a victim of  scams. Trading uses talents like skills and tactics in marketing. Praying won't help on this type of area. We all know that to be a good trader, you need to experience failures, so that next time you encountered scammers you'll know to handle and to avoid it because you knew how scammers act.

No one is bound to have no failures unless if you are really lucky. Every one of us needs experience to learn.
If you failed because of scams and lost all of your assets, it might be dissapointing but it is not the end. The next time you do it, you'll know what to do because you have learned from your mistakes. You may even become a good trader and achieved success in the near future.
