For me gambling has very big problem when can't give up it and continuously losing money for very little hope after this i will get recover all my loses, yes that kind of thinking is very big problem and that is so many people think it is totally wrong.
My thinking is often like that. Always chase the wins then tell myself I'll stop after breaking even but I never do. That leads you into bad situations and you can only blame yourself
Who else can we actually ? So yes its completely our mistake. I have the same tendency too, I once lost money get frustrated and try to recover that from more and more bets and unfortunately leading to big loss.
