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 ;(
What are you trying to imply on your statement? For me, gambling is never a sin because I know how to control myself, I live into the definition of gambling which is entertainment and I am very happy that I found a wonderful site which I am currently playing now, it's non other than FortuneJack.
I believe your luck will just come especially when you have a good experience in playing a certain gambling sites.
