Only those weak people blame other why they came to that situation and loss their money.
You can also add people who can't accept the fact that they made a mistake and wanted to put the blame on other people. I hate these kinds of people who avoid responsibility for their action.
If they just control their self not to gamble or limit their activity provably they will not came to situation where they regret it.
But obviously, they are irresponsible people so it is not a surprise that they can't discipline themselves when engaging in gambling activity. They think that they can put the blame on someone else if worse came to worst.
Also we should remember that over expecting anything on gambling we can be rich or get passive income will not result to anything. Much better if we just enjoy the flow and leave some other greedy thoughts and for sure we can enjoy this.
Gambling result is random and over expecting would be the start of the gamblers' many problems. The moment we press the button we should have accepted the possibility of losing. It will not only lessen our stress but also help us avoid chasing losses.
