Plus, the casino caps the amount bet on the even-money bets to $5000, so even if you're rocking with lots of money eventually you're gonna lose enough times in a row to where you can't double your next bet. 
  
 I guess you could request a high-limit game, but then you're just digging your hole deeper.

Also doubling the bet does not equal 'in the money'. Starting at $2. Your $128 bet that finally wins, only  gets you to +$2. As the previous 7 bets you lost total $126. (2,4,6,8,16,32,64).  
 I actually though about trying this at roulette when I was younger.
