A few more explanations regarding the strategy:
1. The bet is not always black. You can also bet even/odd, high/low, examining the previous outcomes.
2. Be patient. Whatever you've started to bet, be patient. There will come a moment when that even bet will come more, and that is the moment you've expected. Back upwhen you have earned a few dollars in a few minutes, ( or more dollars, if you've started with a bigger bankroll).
3. Always wait a full 24 hours before you play again.
4. Play on multiple casinos, that give you sign-up bonuses. That way you will win more, but have nothing to lose.
5. Don't get greedy!
