I had the victory story but it was a nightmare for me too. Back in 2015, I won a big amount of 1btc in gambling. I was so excited to spend it somewhere. I thought let's put all the money into gambling become more greedy to win more bitcoins. In just one night I lost my all bitcoins. It the nature of gambling eighter you won or lost but I believe it depends if you're greedy you can lose more than your expect
