I think blackjack game is a good method to earn some bitcoins,but play only for short time and don't bet more than can't afford to lose.
I have heard that blackjack gambling has lot of scientific approaches to make it winning on our side. Lot of reference are available on internet still I fear to play as it may addict me. I always gamble for small amount bets for the pleasure of gambling.
Yes correct once you start playing every day and if you lose some money initially then you will try to get back money on daily basis and slowly you will be addicted to it.
