What’s the biggest gambling loss you’ve ever had, and what mistake led to it?

[shanz]

I remember my loss, and actually it was very small compared to others. This helped me learn what can happen when I decide too quickly. The problem is, even years later, I still struggle sometimes because of emotional betting (or even greed). What’s your biggest loss in gambling, and what caused it?
