In my opinion gambling becomes addiction because of if i have been losing it make me curious and that is make me addiction of gambling.
It drags me to gamble too, but also important reason why i and other gamblers gamble is because they can earn a lot of money this way even if it's risky
The exact problem is with me also, when I quit gamble after giving some huge losses I decide that ok enough but then I think hey I ended on a loosing streak, maybe the wins were on the door knocking and that makes me bet more and more, if lost I think ok maybe next and if I win then well,who ends while winning ?
i frequently end my game session while in profit , but a couple minutes ago i have played blackjack and roulette on fortunejack turn a little amount of 4.5 mbtc to almost 80 mbtc as i think it was extra money i keep doubling the bet amount , unfortunately this time i didn't have luck enough to stop while in profit , usually if i play with non-extra money i withdraw the whole bitcoin immediately , in my case i feel i'm not addicted as the reason why gambling addicting are the feeling you get when tempted to get more additional money and to chase the losing money.
