My luck wasn't too good, I've lost around 2 BTC in total in 2016, with around 10 BTC wagered.
I'm definitely going to cut down in 2017 :p
We all think the same, but actually its not luck but its the nature of gambling that we loose all our money. I might sound horrendous but guys god exists, do some good deeds and you get rewarded while I did something bad with someone on many occasions and got punished ;(
