My big balance could always recover
The odds are fixed and are the same for everyone, so it will be not harder to lose, you will win/lose in the same proportion as everyone else the only difference if you keep making the same bets that you did when you were poor is that your bankroll will be less affected by the possible losses.
The question is, will you still be satisfied making the same amount of bet now that you have more money to spend? Will the thrill be the same if you are just betting a few hundred satoshis like when you are still poor? In my opinion, the amount you will bet will proportionally increase with the amount of money you have now. So, there are still chances the you can lose big and lose all your money.
