I would say that $100 is my minimum amount to budget when visiting a casino. When playing withR$100, the only table game I would be interested in playing is roulette, and only if the bet isR$5 minimum or less. Only getting 10 spins at the table is not my idea of a good time.

Keeping your bets within 2-5% of your bankroll is likely more important than whether you bet the same amount every time.
