Gambling should be done for fun and not fod profits, because the casinos are out there for business. The house edge will always win and no matter the amount of money that you use to gamble, it doesn't change anything but increase your losses. Whenever I am gambling, I take it that I have already lost the money that I am using to stake my bet.
It will always happen to illegal casinos that are not clear about the Audits being conducted, unfair RTPs and such.
But for casinos that are already legal and get certified, some online casinos like the ones we use on this forum provide an advantage for those who are lucky and have good skills in gambling.
Casinos are also used as a place to make profits for some people or those who are already professionals,
such as in soccer betting and card games that require the player's skills to manage data and various tricks that need to be done.
The most important thing is how to manage your gambling allocation and your Psychology so as not to be too greedy and stick to the main strategy.
Greed will be the path to an addiction that will make things worse.
Everyone has their own strategy still in betting or other games, the important thing is that you are responsible with your bets and losing it is normal, but making more with combined luck is incredible.
