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
If gambling has a manual, I do believe casino and betting website would all close down but because Satoshi won a lottery doesn't mean the same with happen to Craig-the-Lier,
this is how gambling behave as it changes, if you observe very well in betting, when a gambler win a pattern, they rarely occur again and even if they do, it doesn't have the same chances and when casinos and betting platforms notice, they switched it up and then people who came last to win using the same pattern will give back to the money casino have lost to the player.
Casino and gambling don't make their statistics public, you rarely see their wallet and when they do, its only their Bitcoin transaction you see, they don't display amount that comes into casino and goes ou because Fiat don't have an explorer that you can use to check this statistics, this cannot be use as a tool IMo.
However, every gambler need planning, they need to measure the risk of the outcome of the match before they push in their money to play any bet, because a gambler is winning big amount of money doesn't mean you have to increase the money for staking/wager bet, you don't know how financially stable other gamblers are, and moreover you can't say specifically the source of their capital.
