People don't have statistics to play gamble and that is why some of the gambling enthusiasm do experience (shege in gambling... meaning much loses in a gambling) so it's good for gamblers to know a specific amount that should go out in their wallet weekly or monthly.
When you check the statistics of who is on constant gambling of different kind of gambling either casino, poker game and other gambling games, should check the funds that goes out of them monthly because of gambling and they funds they received in a month and annually in gambling if they are of the same amount.
If we planned our gambling bet we should not be going crazy after when we have not meet up our target in gambling, what i expected every gambler is to make table of how much should be spend in gambling and how much should go investment, because money we loses in gambling continuously if we gather it together it will sum up to start a little business. I'm say play gamble with experience, don't use all you have for casino gambling
A good observation and advice by the way, but generally speaking now, I do not see a difference to honest, it is already widely believed and accepted that casino will always win in the long term in the life of every gambler, having this in mind, whether a gambler chooses to gamble with a very small amount or choose to gamble with a large sum, it doesn't really matter, like you've pointed out, its all about the gamblers target, the gambler might be targeting to win big, if he or she wants big winning, he sure has to put a reasonable amount on the stake table, but for those who don't really care about how much they win, then to avoid making too much loses, then you advice is good for them.
But again, I must not forget to point out that its not a crime of gamble with big money, as long as the gambler can afford it comfortably, and also will not fret or go A-wire if he or she loses the money.
