i thing you should always use a little amount of gambling, you should play gambling with your pocket money, and to invest your all assets in gambling because gambling is a risky game and you can loose your all money in no time.
You are right with it and I think this is the best strategy in gambling especially when you want to be play safe with gambling.
And you are just going to gamble what you afford to lose and then if you are going to win big amount with it then you are one of the luckiest gambler alive.
If this is an effective strategy then keep on doing it again and again.
