As a gambler, having a steady income can certainly have its disadvantages. Gambling is inherently uncertain and risky. While you may have a steady income for a period of time, there is no guarantee that it will continue. Your income can fluctuate drastically, leading to financial instability.
It could only be too risky if you can't handle yourself. If you have a steady income and you are gambling more than you can afford to lose or without a limit, eventually you'll struggle financially. However, there's a higher risk when you are gambling without stable income, as that demonstrate how irresponsible you are, you can't afford to gamble and yet you force to do the biggest mistake as a gambler.
Sometimes, when people make mistake like this, they tend not to accept their mistake, instead, they'll blame gambling for it, and that's the reason why gambling look bad on some when it's just an entertainment in reality.
Taking the responsibility of the mistake may have saved the gambler from too many troubles, but only few persons would admit that what they did is wrong. The human brain, may I say, is wired that way, but if a person is humble enough to take corrections, he wouldn't find himself in a tough condition as spending all his money, all the time. Gamblers with steady income have to be careful not to ruin their financial economy. Because gambling can take out all the money, they've got even their savings if the player is not being serious with money management. Although when done the right way the gambler would have nothing to bother but enjoy the advantage of having extra income to fall back to when gambling. However, not gambling to replenish his funds whenever he's out of bankroll. A gambler need to have a certain amount of money allocated to gambling each month. That way he wouldn't be at risk of spending his income on gambling.
