That's why I said in my previous post that there are no exact figures where we can say that the amount we are betting is afford to lose. There are times that we are exceeding our limit because there's adrenalin that tells us that we need to bet more against all odds.
It's so easy to say that to bet only the amount to afford to lose but in reality, I am sure that 90% are not able to follow that principle especially if the gambler has $2,000 monthly earnings as per OP's example.
Well, that depends on how good you control yourself. Many of us already break that rules because of the thrill from the games but if we really want to control ourselves and money, we must do that. Otherwise, we will regret it later because we will not easily recover our losses even if we use more money to take it back.
I know how it will tempt us to use more money to gamble, especially if we can win a lot of money in a row but we should not forget always to manage our emotions and know when we must stop the games.
The way you gambled will define the way you will spend the $2k on gambling. Since am prone to gambling, I will likely map out about 600 dollars a month. The remaining balance will be on settling bills and enjoying life. $2k is huge money, removing 600 dollars a month for gambling will do me no harm. There are chances that I might win some betting before the 600 dollars finishes for the month.
Geez, using $600 a month for just playing gambling will not give you a chance to win many gambling games. Besides that, if you use that money for your daily life or save that money or invest in other coins, that will give you profit in the future, especially if you are constantly doing that. But that is your call and we can not do many things except remind you not to use too big money for gambling.
