I don't know your worth but 100 dollars is not small amount compared to my status that why I can't wait to lose the amount before I can stop because to me his very huge to be maximum, I only considered maximum to be like 30-40 dollars because per dollar in my own currency is enough to take care of a plate of food.
$100 is viewed differently for different types of individual because of the country they are living in. I can not lose $100 too because that is a big money in my country, I think people in the United state, UK or Canada can say they will lose that amount but still continue gambling because the money is small. These countries have a high salary and people can make that amount from just doing some grocery store works in a day or week the most if I was to do that same job, it can take me more than one month before I can get paid that amount. As gamblers, we just have to avoid being greedy and we would not be losing soo much when gambling. I can not say an exact amount that is okay to use in gambling so that when you double it, you should stop but everyone should do what is best for their money.
