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
Unfortunately, a similar situation happened to this user:
With a bet of 300 Dogoins, I won 496,500 Dogoins.
And the very next day he lost everything:
I lost all my money in games
Unfortunately, greed is the player's greatest enemy. Therefore, before we start playing, we should always make a game plan.
