There is not a single gambler who has never experienced losses, losses is something that is bound to happen. The size of the loss depends on how big a deposit we make and whether we like to chase losses or not. I never deposit much so usually I will spend around $50 in one session, if I get emotional sometimes I will chase my losses and deposit another $50. If I have made two deposits and still lose then I will stop and gamble again next week
Managing your deposits is so important when you're gambling, even if you wanna put in as much as you want. You gotta be wise about it to handle the ups and downs. Losing is just part of gambling, so your idea to set a limit per session is real smart. It ain't just the size of the deposit, but more how you handle yourself and gamble responsibly in each session.
