I took a quick look at the logs and I am wondering if you were using some type of bots to make these bets. Its certainly possible to make 2943 bets by hand however from what I can see the bets are spaced apart by 3-6 seconds or so. I haven't found any large gaps in the logs which might indicate you took a break to go to the restroom or what-not.

So I am assuming you used some type of bots and maybe you forgot to shut it off and it kept betting for you by mistake until it drained your balance. Did you use some type of API with a custom made bot or were all these bets made manually with actual mouse clicks?

This is the only thing that makes sense.
