My gambling strategy is that don't bet too much just bet in small amount and just enjoy of what you are doing. Don't put all your allowance in gambling so that in the end you will gonna blame yourself. 
Well, i think you are gambling only for fun with small bets.. Because some people go gambling because they want get profit and doubling their money so fast.
But not all people are lucky to double their money in gambling. Some people are always loosing their money because of gambling so I guess it's much better to just put a small amount when betting so that win or loose you will blame yourself if you loose all your money.
