You need to be careful because it's a sign to be a gambling addict if you deposit more money and you angry after you lose all of your money. Try to learn if gambling isn't for making money, if you think 15% of your income is big for you, you can reduce it to 5% or lower. In case you lose, it will not hurt you.
Remember, curing a gambling addict is really hard, prevention is better.
