I guess the next topic will be about the 74 rules of playing slots...

How does gambling go for you? Have those courses helped you? You are writing about something you have read, but I don't see that you're actually gambling and that you are writing something from your personal experience. Someone inexperienced would be asking the question "what's more profitable in gambling?".

No one knows what is more profitable until they try it. So try it for yourself and you will find out what is more profitable for you... after that, you can share your experience with us & your conclusions.
