mine was $200,000 on Stake.com 2 weeks ago
That's huge money to lose in one session, but what can I say? I don't have that big money to begin with. But during the height of my addiction, I would say that I will go and lose $1k at least in one sitting in a card game in a land base casino. It's just a short time, maybe I was really unlucky that night that it was very quick and then I say that is the only money that I will lose, then next thing I know
I will have to go to a ATM machine and withdraw more, again and again. So it was really hard to control once you taste that defeat and wanted to recoup and recover. Anyhow, not sure how are you going to be affected losing that big money and hopefully it's a money that you can afford to lose.
