What you describe may be possible, but getting 3%-5% profit from gambling cannot be obtained in a row. The risk is that we can lose all the money
we have, if we play excessively or we can't control our greed. It's not a new thing experienced by many gamblers, if win we want to get the next win,
and ended up losing all our money. So don't be obsessed with winning when playing gambling, because it will cause us to lose a lot of money.
Just enjoy the gambling games that we do, if we do win, we must stop immediately and withdraw the profits we get.
There are many gamblers who suffered from this kind of experienced, thinking that they can quit after winning their small target.
But after filling that out they continue to try winning more, the outcome is not good since instead of winning
and enjoying they just lost it back together with their capital.
Better to enjoy your game and treat those winnings as additional incentive if you manage to win some from the house.
We could really have those kind of limits that we do have set before we do able to play but once we had already gambled then stopping mid way is always been the problem on where people do really
failed to stop theirselves and would get addicted after wards on where they do spend up money that it shouldn't really be spent in the first place or simply going beyond into their budget.
When you do gamble then set limits and when its total lost then don't tend on adding up and this is kind of the behavior on where a gambler must have.
