This question may seem a little silly...but bare with me. For the pros, after a winning session/s of blackjack.....do you keep all of your winnings and add it to your bankroll? How do you go on about this? or do you keep a certain percent of your winnings for personal use? I was just curious, I didn't know if you had a formula or way of determining how much money/units you keep for yourself for life outside of blackjack, or if you just add onto your bankroll. Thanks.
