How does one control the balance of there account when 99% of these apps have casinos & other ways to gamble your money making it always very enticing to try to win more after already winning.
Ignore that siren song and stay well away from -EV bets. When dealing with -EV gambles, you're a winner if you
don't play. I never play them. Period. No one's putting a gun to your head forcing you to click on the casino section, so don't do it.
"Not to say I haven't hit the blackjack table harder than I should have a couple times when I was younger... But that money was already ear marked for booze, babes and BLACKJACK!!!"
That worked until they caught on and started kicking me off the Blackjack tables. That's when I decided Poker would be the better option. These days, Blackjack really SUX, between the auto shufflers, the 6 : 5 payout for getting a Blackjack, the ridiculous cut card placement, you're not likely to see a good game.
