Starting out with $100 - advice needed

[Snoh84]

The best way to beat microstakes is bonus whoring/rakeback. You can be a profitable player, but at the stakes you're playing, you'll make just as much through bonuses. If you haven't made a real money deposit on sites, usually you still qualify for bonuses.

Far and away the best advice I can give you to build up your bankroll from $100 is if you ever lose more than $10 in a given session, quit. When you are first starting it is super-easy to lose it all in one day tilting or not caring.
